Getting error "bad indentation of a mapping entry"

[kailynnelson]

When following your 'Setting up' instructions, step 3 says to paste your Actions code as-is. However, when I do that, I get this error message:

bad indentation of a mapping entry

and my workflow fails to run.

What am I doing wrong?
