I don’t know why it’s not passing for you. I forked your repl and then added the MESSAGE_STYLE variable to the Secrets tab and it passed for me.
I presume you’ve added the variable to your Secrets tab?
Thank you for your reply.
The problem seems to have been that I set the variable holding the text “Hello json” outside of the handler. Since I defined the variable in the handler, the test executes sucessfully.
