Bug in 2.4.0: UnboundLocalError: cannot access local variable 'user' where it is not associated with a value

[gusttt]

Hello,

Thank you for your plugin ❤️

When using the just released 2.4.0 version, the github action fails with the below error. When using version 2.3.0 the error does not occur.

INFO    -  git-committers: fetching contributors for docs/index.md
ERROR   -  Error building page 'index.md': cannot access local variable 'user' where it is not associated with a value
