Want to use over 200+ MCP servers inside your coding tools like Cursor?
I'm working through Nathan’s Workflow for the n8n course level 1 and encountered the error:
"Please provide the correct Unique ID" in the HTTP Request node.
I followed the course instructions closely but still get this error. Any help resolving this issue would be appreciated.

Based on the tutorial instructions in the course, this error typically appears when the HTTP Request node doesn't receive the expected Unique ID as part of the request header. Here are some steps to troubleshoot:
1. Verify the Header Field
Make sure that in the HTTP Request node you have:
- Send Headers toggled to true.
- Under Specify Headers, the Name is exactly
unique_id(all lowercase) and the Value is the Unique ID you received via email.
2. Check for Expression Issues
If you’re using an expression to insert the Unique ID, ensure that the expression returns the correct value. It might be helpful to temporarily replace the expression with the actual Unique ID (copy-paste from your email) to rule out syntax issues.
3. Confirm Email Details
Double-check the email you received when you signed up for the course. The email contains:
- The Dataset URL
- The Unique ID
- The credentials for Header Auth
Ensure that the Unique ID you are using is exactly as provided, with no accidental extra spaces or missing characters.
4. Header Auth Considerations
If you’re using Header Auth (under Authentication > Generic Credential Type > Header Auth), verify that the credential details (name and value) you’ve entered there match the instructions in the email exactly.
Summary
- Verify that the header parameters are set up exactly as instructed.
- Test by using the Unique ID directly instead of through an expression.
- Confirm that the email details have been copied correctly.
Following these steps should resolve the "Please provide the correct Unique ID" error in your HTTP Request node. Happy automating!
