OpenAI Analyze image node truncating it's output

[Daniel_Reis]

Describe the problem/error/question

I’m experiencing an error while using the OpenAI Assistant Analyze Image node. The output almost always gets truncated, and I don’t even know how much of the answer I’ve lost…

It seems to be related to the size of the response. But anyway, it shouldn’t do that (right?).

I’ve tried with GPT-4o and GPT-4o-MINI, both having the same problem. Is anyone else going through the same issue?

Any hints on how to fix this? Maybe something changed on OpenAI’s side…

What is the error message (if any)?

No error message…

Please share your workflow

The output should not be truncated.
