Apple Wallet Passes GET request with undefined authorization params from wallet device

Hello! I am getting undefined in the values ​​of authorization and passesUpdatedSince when devices send a GET request to the v1/devices/{deviceLibraryIdentifier}/registrations/{passTypeIdentifier}?passesUpdatedSince={previousLastUpdated} route. Should I double check any settings? Because if I test it trhough postman works like a charm.

POST or DELETE requests to v1/devices/{deviceLibraryIdentifier}/registrations/{passTypeIdentifier}/{serialNumber} to work perfectly from device as well. Both receive the correct parameters from the device and can be authenticated to execute the corresponding methods.

I hope I have luck in getting some guidance :) Thank you!
