My OpenAI assistant via make don't use the existing uploaded files

Hi everyone! Does someone know how to answer this question? There is no way I can build this scenario where my GPT assistant (running on 4o) recognizes a document. I tried uploading it to the knowledge base and also referring to it in the messages. I got a message from my assistant saying it does not recognize the file. Simple flow I am building: As soon as a document is added to a specific google drive folder, it needs to be sent to my gpt assistant for follow-up questions…any clues? I did this many times before, but I can’t seem to make it work this time (after 4o updated module)
