Failed commit signature using Github Application

[CCOLLOT]

Problem statement:

When using a Github Application to write changes to git, commits are not signed.

Error message:

remote: error: GH006: Protected branch update failed for refs/heads/main. remote: remote: - Commits must have verified signature

According to the documentation:

Signature verification for bots will only work if the request is verified and authenticated as the GitHub App or bot and contains no custom author information, custom committer information, and no custom signature information, such as Commits API.

I tried setting .Values.controller.gitClient.name and .Values.controller.gitClient.email to "" but it did not solve the issue.

After looking at the code, it seems that if those values are empty then Kargo will use default values.
I wonder if removing those default values would solve the issue
