400 Invalid Assessment_id en endpoint company-warehouse (curso QS101)

n8n Academy QS101: n8n Quickstart
1

I’m taking the QS101 course (n8n Quickstart) and the HTTP Request node that calls company-warehouse keeps giving me the following error:
400 - {“error”:“Invalid assessment_id.”}
I’ve already verified that:

  • My email is confirmed
  • The x-assessment-id header has my current Assessment ID: 59c60db8163c5020d34f6a6c5f9f40b2
  • The Header Auth credential (X-API-KEY) is configured exactly as the course indicates
  • The URL is correct: https://learn.app.n8n.cloud/webhook/courses/n8n-quickstart/company-warehouse
    The course’s AI assistant confirmed that my node configuration is correct, and that the problem appears to be on the server side (my ID is not being recognized as valid/active).
    Could you check if my assessment ID is correctly linked to my account? Thank you in advance.

good morning @janvanegas

That error Authorization data is wrong! usually points to authentication, not to the Assessment ID itself. In QS101, that endpoint needs to receive both headers: X-API-KEY and x-assessment-id. There was a similar case in the community where the Assessment ID was correct, but the X-API-KEY wasn’t being sent by the request. I would first confirm whether the Header Auth credential is actually selected in the node and whether both headers are arriving in the call; if they are, then it would make sense to suspect a problem with the Assessment ID binding.
