Because of problems with credentials I have been switching back and forth a lot between the Request Library and the Axios Request Library using the
N8N_USE_DEPRECATED_REQUEST_LIB environment variable.
I ran into a problem where I receive a
'source.on is not a function' error when trying to upload a PDF-file using the SalesForce node.
I switched back to
N8N_USE_DEPRECATED_REQUEST_LIB=false and this fixed the problem. I believe there is something going wrong when uploading a file with the new Axios request library.
Node: SalesForce (Document Upload)
