Logging. Message: Login failed. Not found

Good afternoon everyone!

I am trying to set up fail2ban. According to the logic of this application, it looks at the log file and works according to the template.

But in the log file there are no events of type “message”: "Login failed
I tried to simulate login errors and only information was written to the log:

{“reqId”: “YcGQi08XnWJJF8PgDV7PgQAAUgo”, “level”: 1, “time”: “December 21, 2021 12:30:07”, “remoteAddr”: “”, “user”: “-”, “app”: “admin_audit”, “method”: “POST”, “url”: “/ index.php / login”, “message”: "Login attempt: " username \ “”, “userAgent”: "Mozilla /5.0 (Windows NT 10.0; Win64; x64) AppleWebKit / 537.36 (KHTML, like Gecko) Chrome / 96.0.4664.110 Safari / 537.36 “,” version “:” "}

Can anyone suggest why there is no entry - message: Login failed ?
