Hey there!

I had the sam issue - it’s something with the formatting of the message. It’s very strict and most probably incorrectly provided in the course, which results in this error. Or there is some other error which is not really ours to deal with.

Anyhow, you don’t really need that operational to complete the certificate, so carry on - you did what’s needed here :wink:

Mark this as solved if it helps!
