Exception in ASGI application

[crazyelectron-io]

When transcribing an audio file (ac3 format, extracted from mkv with ffmpeg) it generates an error:

It's an english language audio file and when trying translate to nl it gives the same error.

You can’t translate English to NL. You can only TRANSLATE into English or transcribe into the same language.

The Docker GPU version I am using has the following issue. The same audio file is using the Docker CPU version and there is no problem.
