We are trying to add a file for fine-tuning using the API OpenAI API. We want to do this on our Google Apps Script app Apps Script | Google Developers.
Seeing the method docs and samples, it seems like we can only provide the name of the file, which would exist locally. I tried creating a jsonl file on Apps Script, using our dataset, and providing the file blob, but I get a 400 error.
Is there an alternative way of inserting a file with the API?
