1. During local tests both phpunit and behat passed OK
2. Under my repo all steps passed OK except backward redirect (disabled now): https://github.com/semteacher/moodle-payment_gw_mpay24/actions/runs/11969473949.
   Besides, even in that cases - user being redirected back and respose processed properly:
   
   Screen is from GitHub - I have empleyed actions/upload-artifact@v4 to retreive it.
   So all is OK except some JS or crashed or unresponsible. But it is necessary to catch bronsers console / network dump somehow from github. And I do not know how to achieve it now.
3. Finally - does repository secrets had been added there? Text of the error " The merchant ID '' you have given is wrong, it must be 5-digit number and starts with 7 or 9!" pointing that it did not.

@georgmaisser How should we proceed?

[georgmaisser]

I added secrets and retriggered this job: test (8.1, MOODLE_405_STABLE, mariadb)

Let's see if it works with the secrets

@georgmaisser Still failed. My fork passed https://github.com/semteacher/moodle-payment_gw_mpay24/actions/runs/11969473949
