Error Messages

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.

API Key and Billing Errors

Troubleshooting

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.

Maps JavaScript API Error Codes for Developers and Site Owners

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.

Map Loading Errors

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

Maps JavaScript API Error Codes

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.

Developer Error Code Type Description

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.

SignatureNotRequired Warning

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.

SignedInNotSupported Warning

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.

UrlAuthenticationCommonError Error

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.

Checking Errors in Your Browser

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.

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.

Handling unsupported browsers

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.

If your code still isn't working

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.
