Additional context

Seems to be connected to:
command ["ios-deploy", "--debug", "--id", "a2f8335b5f4f93166ec5c55523f038ae17a8f63d", "--no-wifi"] exited with code 1

Interestingly, the App gets Pushed to the Device, and can be Opened and Accessed, when a reachable Dev Server is running and the initial "Allow Network Access" Request has been accepted the first time. (Via the npm run dev -- --host Option).

But when starting it over IOS Deploy it seems to fail immediately.

Could be connected to the Version the Device uses which is quite Old:
Model: iPhone 6s
Software Version 15.7.3

[Genei180]

The Error seems to be related to a Missing Flag, telling ios-deploy where to look for the App Bundle:

When Testing the Provided Command Manually it Fails with:
