Avahi service won't add my scanner for Epson dx7400 series

[mketizmen]

Hello, I tried to use your program for making my scanner in my Mac but I cannot see my scanner in add printer scanner settings page. After a little research I saw my scanner won't add in avahi service. I tried to use web client and I found my scanner as CX7400 in web and can make scan file, preview file. I look tags in git hub for find latest working version but as I see you didn't use that option can you help me?

My system Debian buster and updated latest versions in docker.

Could it be that your avahi-daemon is not running? That is indicated by the "Bad State" result when trying to add the service.

I checked avahi-daemon and be sure about its running but can't add service

I improved avahi error handling a little. Could you run the latest git version, and tell me which error is reported instead of "Assertion 'client' failed"?

Thanks.
