Uncaught TypeError: AWS.EventBridge is not a constructor #4289

Hey, I have the following code. Similar to the guide for in browser Polly implementation from the official docs I have tried to create a script that interacts with EventBridge to enable a rule. When I tried the Polly implementation from the guide, all worked well. So I tried to make a similar solution to use EventBridge:

<!DOCTYPE html>
  <body>
    <div id="textToSynth">
      <button class="btn default" onClick="activateService()">Activate Service</button>
      <p id="result">Click button to activate service</p>
    </div>

    <script src="https://sdk.amazonaws.com/js/aws-sdk-2.595.0.min.js"></script>
    <script type="text/javascript">

        // Function invoked by button click
        function activateService() {
          // Initialize the Amazon Cognito credentials provider
          AWS.config.region = '...';
          AWS.config.credentials = new AWS.CognitoIdentityCredentials(...);

          // Create the EventBridge service object
          var eventbridge = new AWS.EventBridge({apiVersion: '2015-10-07'});
    </script>
  </body>
</html>

However, when I try running this code by pressing the button, I get the following error:

tgtg.html:24 Uncaught TypeError: AWS.EventBridge is not a constructor
    at activateService (tgtg.html:24:29)
    at HTMLButtonElement.onclick (tgtg.html:10:63)

I am able to interact with any other service I have tried so far, but I cannot seem to use AWS.EventBridge at all. Am I doing something wrong or is EventBridge simply unsupported by the AWS SDK JS, and they just forgot to document that?

I have tried changing the version for <script src="https://sdk.amazonaws.com/js/aws-sdk-2.1264.0.min.js"></script> and tried others, however, it threw the same error.

However, it worked when I tried building my own AWS SDK with EventBridge included through the link you provided.
I downloaded a minified version and put it on my web host in the js folder, then replaced the line above with <script src="js/aws-sdk-2.1265.0.min.js"></script>

The browser build only includes services that support cross origin resource sharing, but its not enabled for EventBridge. We maintain a list of supported services with a notation on which allow CORS here

I had predefined code to check the behavior but it used custom builds too but https://sdk.amazonaws.com/js/aws-sdk-2.1264.0.min.js should not work because of the reason mentioned above.
