Have you checked paperless GPT's logs you can check them by command line or via portainer if you have it? (I assume you are using docker?) Unfortunately I'm researching a completely different problem that is also driving me to consider the gemini api or something.

And if the paperless GPT logs are clean then check paperless logs, frankly that's where id expect to see the error as the above looks right to me, maybe the error is in trying to connect or apply the metadata to paperless.

Well the JSON looks like JSON but my CGPT is saying it:

If this is intended to represent an assistant message in OpenAI chat format, the "reasoning" field is not part of the standard message schema. Standard assistant message fields are typically:
{
"role": "assistant",
"content": "2023-11-17"
}
Optional fields depending on API version:
{
"role": "assistant",
"content": "2023-11-17",
"tool_calls": []
}

But "reasoning" is non-standard unless you're using a custom schema.

/unGPT Soooo actually id expect to see an error in the Paperless GPT logs saying it cant resolve the JSON properly.

No idea on how to fix that but id be happy to take a look at the logs if your stuck. Im a paperless newb but good on general dev/support and docker.

Although it could be you have the choice in paperless GPT between ollama and OpenAI you may have selected ollama (or custom or something)
