File upload via REST api + Form data giving me invalid header error

Hi there, I am trying to upload an image via rest api using the form data body. It is giving me an invalid header name. Does anyone know why?

@victoria Do you happen to know the answer to this? I have been reading your threads in regards to this :slight_smile:

Hey @mmondragon!

Would you mind sharing a screenshot of your resource setup page? Feel free to send it in DMs if it contains sensitive data :slightly_smiling_face:

I'm not seeing any headers being sent from the query itself but there might be some sent by the resource or some that are default Retool headers.

Another great place to check is in the request preview:

It might also be helpful if you have some documentation on the API you're trying to hit in case there's a hint there about what may be getting rejected.
