wtype in systemd service call not working for the same user (raspbian)

[nick-mitigo]

Dear all,

I just faced an issue with wtype. If my application is started from the console (probably with all of the env variables) it works nicely.
However if the app is added as a service to systemd it's not responding and no error coming back.
I suspect some missing environment variables - what would you check first?
Running on RPI5 (6.12.34+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.12.34-1+rpt1~bookworm (2025-06-26) aarch64 GNU/Linux)

Thanks!
