Had similar problem with similar message. This is how we found out what was wrong:
Executed
check50 -h
to see what logging options there were. Discovered we can turn on debug logging using--log-level
option.Executed
check50 --log-level debug path/to/folder...
. In the output noticed:fatal: repository 'https:///github.com/me50/$USERNAME'USERNAME' not found
.Navigated to the repository URL in the browser:
https:///github.com/me50/$USERNAMEUSERNAME
Had to click "Accept Invitation" from
bot50
.Executed
check50 path/to/folder/...
and it worked fine using username and GitHub personal access token (instead of password).
