I think that chirpstack-concentratord-sx13012/src/config/mod.rs:282 sets the default device to "rak_2287_eu868" but this device is not provided in the block starting at line 325 of the same file.
Result: if started without a config file specifying the correct device, throws a panic "unexpected gateway model" in line 345.
Solution: change the default to a valid device, or tell the user the use a config file.
The issue is present in the latest release.
