@Valeri12580 could you try to merge my branch with the changes and verify if it works now?

It looks like the formatting job is fixed but the "Test" from backend and Lint from frontend are still failling.

Hi @Valeri12580 oh, yes. I check this.

Hi @stritti, It looks like this job is failing too:
https://github.com/Sybit-Education/Diveni/actions/runs/6597906565/job/17941827562?pr=426

I'm not sure why it is failing but I see that you added it recently

Hi @Valeri12580 I created now a fork for better verification.

What you noted at #456 (comment) is caused by warnings in frontend. I solved this in the new PR too: #483
