Describe the/error/question

Have spent more time than I care to admit trying to understand this error. The handshake for my webhook seems to take place but for some reason I get no failed exexcution on n8n’s en

What is the error message (if any)?

Error message / console is:
:rocket: Sending webhook to: [redacted]
index-DS1Ok68_.js:70 :package: Payload: {location: ‘Mexico’, interests: ‘Food’}
index-DS1Ok68_.js:70 :outbox_tray: Sending POST request…
index-DS1Ok68_.js:70 :inbox_tray: Response status: 500
index-DS1Ok68_.js:70 :cross_mark: Error response body: {“code”:0,“message”:“There was a problem executing the workflow”}

Please share your workflow

The issue is with your webhook node. There are two actually:

  • each header is prepended with invisible tab character, they need to be removed
  • there is an empty header at the bottom, it needs to be removed
