Hey guys.
I’m having trouble uploading a PDF to a XERO invoice using an HTTP request in n8n.
Here’s what’s happening:
-
The HTTP node receives the binary, but the request just hangs and eventually times out after 5 minutes (n8n timeout).
-
XERO’s request history doesn’t show any incoming calls, even though my credentials are set up correctly in n8n.
-
The same request type works fine in Make and Postman, and I’m using the same n8n credential type as with other organizations where this works.
Could you help me figure out what’s going wrong? Any advice or tips would be much appreciated!
Thanks a lot!
