*I am trying to upload a file and send it with a POST request. No matter what file I upload (pdf, png, jpg…) it gives me the error code InvalidrequestContent and the message "The input body for trigger 'manual' of type 'Request' must be of type JSON, but was of type 'application/pdf'." - depending on the file format.

I tried to upload as binary as well as form-data. Any suggestions?*:
