I am trying to connect the Zoom API with N8N for which I am using HTTP Request node to setup an OAuth2 API connection. I am getting an error in the main http node after setting up Zoom OAuth2 API connection successfully.

ERROR: UNKNOWN ERROR - check the detailed error for more information

401 - {“type”:“Buffer”,“data”:[123,34,115,116,97,116,117,115,34,58,10 …

Hi @SWAPNIL_NANDANWAR, I am sorry you’re having trouble.

This looks like the server returns a proper error message (possibly indicating what’s wrong with the request), but n8n tries to parse this error message as a file.

Can you try setting the Response Format option on your HTTP Request node to “Text”? This should hopeful allow you to read the error message and fix whatever needs fixing
