Can anyone tell me please - how to capture an HTTP error response 404 when fetching an audio resource. I am building in Composer 8.1.201.72.
Custom error on Prompt block
Then
error.whatever-mcp-throws-as-error
This is the general rule for any other error not mapped.
However for 404 errors your app will continue working, just will hear a weird audio which on Pre-Stage tests you should be able to capture and identify and correct.
If you have TTS then you can use it as well as Alternate Text.
