Migration failure when updating to 4.14.1

Describe the issue

Hi all,

We are running Weblate deployed into Kubernetes and tried to update from 4.3.1-1 to 4.14.1. On startup Weblate tries to run the migration which fails with a weird git error.

Starting...
Postgres 120008 is up

[2022-09-21 08:59:58,757: WARNING/53] Handled exception: RepositoryException: Author identity unknown

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

I do not really understand what is going wrong here and how to fix it. Seems like git configuration is incorrect, but I have no idea why it is broken now and how to fix it (git integration worked fine in previous version). Maybe you have any advise? Is there any configuration missing maybe?

I tried to configure git by adding a .gitconfig file in /app/data/home/.git/.gitconfig with a user and email address included but that didn't change anything.

Thanks
