Error Messages | Maps JavaScript API

Stay organized with collections Save and categorize content based on your preferences.

This page describes the error messages that can be returned by the Maps JavaScript API. The Maps JavaScript API writes error and warning messages to the JavaScript console. Certain error conditions may also occur, which result in the display of a darkened watermarked map.

Under certain circumstances, a darkened map, or 'negative' Street View image, watermarked with the text "for development purposes only", may be displayed. This behavior typically indicates issues with either an API key or billing. In order to use Google Maps Platform products, billing must be enabled on your account, and all requests must include a valid API key. For help on finding error messages, see the section on checking errors in your browser.

The following flow will help you troubleshoot the issue.

An API key is passed as the key parameter in the URL that is used to load the Maps JavaScript API. Here are a few options to check if you are using an API key:

• Use the Google Maps Platform API Checker Chrome extension. This allows you to determine if your website is properly implementing Google’s licensed Maps APIs.
• If you are using a library or plugin to load the Maps JavaScript API, check the settings for that library and look for an API key option.
• Check errors in your browser. If you see the following messages, you are not using your API key correctly:
• Google Maps JavaScript API warning: NoApiKeys
• Google Maps JavaScript API error: MissingKeyMapError

• If you have access to the source code of your application, look for the <script> tag which is used to load the Maps JavaScript API. When loading the Maps JavaScript API, substitute YOUR_API_KEY in the code below with your API key.

    <script async defer
      src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap">
    </script>

• Check the network traffic generated by your website in the browser. In Chrome, this can be viewed using the DevTools Network tab. Here you will see the network requests made by your website. Requests made using the Maps JavaScript API will be under the path maps/api/js. Here you can confirm if the requests are using the key parameter. It may be helpful to filter your network traffic by maps/api/js when viewing the Network tab.

To get an API key, click the button below. If you do not see a guided setup, follow the full instructions at Get Started with Google Maps Platform.
Get Started

Great! Let’s move on and check if a billing account is attached to your project.

Go to the Billing page in the Google Cloud console and select the project under which your API key was created. To confirm the key is associated with the project:

1. Go to the Credentials section, which can be accessed from the left side bar under Google Maps Platform > Credentials.
2. Check that the API key you currently use on your website is listed. If that's not the case, switch to a different project, and check the credentials there.
3. If you cannot locate the project for your API key, you may have lost access to this project. Ask others in your organization for help. If the original project cannot be located, you should:
   1. Create a new project. This can be done by selecting New Project from the projects list, or by selecting Create Project via the Resource Manager page.
   2. Create a new API key. This can be done on the Credentials page. Once there click Create credentials and then select API key.

Once you have located your project in the Cloud console, check if a billing account is attached by navigating to the Billing section in the left side menu.

Go to the Enable Billing page in the Cloud console and add a billing account to your project. For additional information, see Get Started with Google Maps Platform.

Great! Let’s make sure the provided billing method is valid.

You can add, remove, or update a payment method in the Cloud console.

If you have set a daily limit on any of your APIs, which is common to prevent unexpected increases, you can resolve this by increasing your daily limit.

You can check your daily limits by going to the APIs & Services Dashboard in the Cloud console. Once there:

1. Select a project if prompted.
2. Select an API from the list, then click the Quotas tab.

API keys with an IP addresses restriction can only be used with web services that are intended for use from the server side (such as the Geocoding API and other Web Service APIs). Most of these web services have equivalent services within the Maps JavaScript API (for example, see the Geocoding Service). To use the Maps JavaScript API client side services, you will need to create a separate API key which can be secured with an HTTP referrers restriction (see Get, add, and restrict an API key).

The following tables list the possible error codes returned by the Maps JavaScript API, with a description of the cause and how you can fix the problem. For help on finding the error messages, see the section on checking errors in your browser.

If you encounter an error while loading the Maps JavaScript API, please see the table below to find explanations for the error codes.

The script element that loads the Maps JavaScript API is not being included correctly on your page. In order for the API to work correctly, it must be loaded directly from https://maps.googleapis.com.

If you find an error on Chrome JavaScript Console, Firefox Web Console or any other equivalent tools on your browsers, please see the table below to find explanations for the error codes.

The Maps JavaScript API returns both errors and warnings. An error indicates a severe issue which occurred while loading the Maps JavaScript API. Your page cannot load the API correctly, and the API will not work on that page. A warning is a supplemental message about the loading of the Maps JavaScript API. The warning describes the possible reasons for an error, or suggests potential issues in your code that loads the Maps JavaScript API. If you receive only warnings without any errors, the API will work correctly on that page. However, we recommend that you fix these potential issues as well.

The Maps JavaScript API is not activated on your API project. You may need to enable the Maps JavaScript API under APIs in the Google Cloud console.

The sensor parameter is no longer required for the Maps JavaScript API. It won't prevent the Maps JavaScript API from working correctly, but we recommend that you remove the sensor parameter from the script element.

The signature parameter is not required for the Maps JavaScript API. It won't prevent the Maps JavaScript API from working correctly, but it may introduce security risks. Please remove it from your script element.

The signed_in parameter has been deprecated and is not supported on the version of the Maps JavaScript API you are using. This won't prevent the Maps JavaScript API from working, but the behavior of your application may change, if you rely on signed-in features.

An error has occurred that doesn't fit into the other categories on this page. This could be caused by a temporary problem. Please retry the request after a short delay. If that doesn't solve the problem, please review the developer's guide to make sure the request has the proper format.

The Maps JavaScript API writes error messages to window.console. This section explains how you can check the window.console output in Google Chrome. If you are using any other browsers, please check the developer documentation for your browser. For your reference, this is a list of tools to check window.console output in some other browsers.

• Web Console for Firefox.
• Remote debugging for Android.
• Web Inspector for iOS.

In Chrome, you can use the JavaScript Console to check window.console output as follows.

1. To open the Developer Tools, select the menu icon > More Tools > Developer Tools.
2. To open the JavaScript Console, press the ESC key on your keyboard. The ESC key will toggle the JavaScript Console. If you close the console, press the ESC key again to open it.

If any errors or warnings occurred when loading the Maps JavaScript API, they appear as one or more lines in the console. An error or warning message has the following format:

Google Maps API error: [ERROR CODE] [Link to API document]
or
Google Maps API warning: [ERROR CODE] [Link to API document]

You can check the error codes table above to find the error code in the error message. You can also find the details about the error message in the API document linked from the message.

Note: You can listen for authentication errors programmatically.

Ensure that the version of the browser you are using is currently supported by the Maps JavaScript API.

If you're developing a native Windows application that runs in a WebView, ensure that you are using WebView2 based on Edge. Previous versions of WebView, based on Internet Explorer, are no longer supported.

To help you get your maps code up and running, Brendan Kenny and Mano Marks point out some common mistakes and how to fix them in this video.

• Look for typos. Remember that JavaScript is a case-sensitive language.
• Check the basics - some of the most common problems occur with the initial map creation. Such as:
  • Confirm that you've specified the zoom and center properties in your map options.
  • Ensure that you have declared a div element in which the map will appear on the screen.
  • Ensure that the div element for the map has a height. By default, div elements are created with a height of 0, and are therefore invisible.
  Refer to our examples for a reference implementation.
• Use a JavaScript debugger to help identify problems, like the one available in the Chrome Developer Tools. Start by looking in the JavaScript console for errors.
• Post questions to Stack Overflow. Guidelines on how to post great questions are available on the Support page.
