Issue not created and Action shows `Unexpected input 'repo-token', valid inputs are ['joke', 'issue-title']` warning

I’m currently stuck on the final step in the Writing Javascript Actions course where there is no issue created as expected in the Issues tab. In the Actions tab there is an error that reads Unexpected input 'repo-token', valid inputs are ['joke', 'issue-title']

I can’t see anything wrong in terms of possible typo(s) and nothing obviously wrong sticks out either.
