N8n level one tutorial not accepting header unique id

[A_A4]

@Elina_Parsa

Hello there , hope you’re all having a good day
I have ran into a problem that was asked in Unique_ID (error Please provide the correct Unique ID.) but I didn’t get the answer I needed
I have signed up for this course and for the second workflow of nathan I recieved an email giving me the credentials , the authentication header credentials work but in the header section when I input the Name as unique_id and the value as the Unique ID that was in the email it gives

error
Please provide the correct Unique ID.

I tried signing up again the situation was the same|I am sure that I’m putting in the correct value , can anyone please help me?
Thank you all so much

If it still fails with the new email/ID, then it’s likely an issue on n8n’s side with your specific ID; in that case, share your Unique ID and setup in the community forum so the team can check the certification database directly (this is how similar cases were resolved).
