403 Forbidden - MissingAuthenticationTokenException

[jmzn]

Hi,

When I start the Stream Webcam from the client app I am seeing a 500 error when accessing the URL API Gateway: https://XXXXXX.execute-api.us-east-1.amazonaws.com/Prod/FrameData.

Details below:

HTTP/1.1 403 Forbidden
Date: Sat, 18 Apr 2020 07:50:55 GMT
Content-Type: application/json
Content-Length: 42
Connection: keep-alive
x-amzn-RequestId: c6a1d40c-8434-4be6-b923-5dba2fb3e34b
x-amzn-ErrorType: MissingAuthenticationTokenException
x-amz-apigw-id: LLCm7FonFiAFXFg=

Can you please help?

Thanks,

Joana.

I forgot to mention that is also looking for a file /js/app/config.js in the webapp S3 bucket which does not exist and it is showing a 400 error when accessing through the url https://XXXXXXXX.execute-api.us-east-1.amazonaws.com/Prod/App/js/app/config.js.

Thanks in advance
