Thanks for the bug report @Andarius!

We've already got a utility to check if the key actually works so this should be a quick fix.

Hello @madkinsz and @bunchesofdonald,

just adding this here in case anyone else encounters:
I thought just giving the key a different name could be a temporary fix, but it turns out this environment variable (with this exact name) has to be set, if not I'm getting errors like: RuntimeError: Cannot create flow run. Failed to reach API and so no flows can run
