Case Sensitivity Issue with 'audioHostUrl'

[devmalcolm]

What happened and what did you expect to happen?

When using the Amazon Chime SDK (amazon-chime-sdk-jsv. 3.25.0) in an Electron app (MacOS ARM64), there is an issue with accessing the AudioHostUrlproperty. The SDK appears to expect the audioHostUrl property with a lowercase "a", while the server response provides AudioHostUrl with an uppercase "A", resulting in a TypeError: Cannot read properties of null (reading 'audioHostUrl'). when using object.audioVideo.start()

Environment:

• Client-Side Library: amazon-chime-sdk-js version 3.25.0
• Server-Side Library: aws-sdk version 2.1691.0
• Client Platform: Electron app on macOS (ARM64)
• Browser Engine: Chromium

Expected Behavior:

The SDK should access the AudioHostUrl property in a case-insensitive manner or support AudioHostUrl in its current form without requiring transformations on the client side.

Actual Behavior:

The SDK throws an error: TypeError: Cannot read properties of null (reading 'audioHostUrl'), because it expects audioHostUrlwith a lowercase "a", while the server response includes AudioHostUrlwith an uppercase "A".

Additional Context: As a workaround, I tried normalizing the keys on the client side, but this adds extra complexity and processing overhead.

Reproduction steps

• Set up a meeting session using Amazon Chime SDK (Electron app in my case).
• Invoke an API call from the client that retrieves meeting configuration data from a server, which uses aws-sdk to create a Chime meeting.
• The server responds with meeting details, including AudioHostUrl (capitalized).
• The client code tries to access object.MediaPlacement.audioHostUrl (lowercase) based on the SDK's requirements.

We convert the response to lowercase here https://github.com/aws/amazon-chime-sdk-js/blob/main/src/meetingsession/MeetingSessionConfiguration.ts#L174 so it should support both lower and uppercase.
Could you try to manually run this function on your server response to see if it does not convert all the properties to lowercase?
