Hi devs!!!
Calling createCredentialRegistrationRequestWithChallenge returns the following error:
Error Domain=NSCocoaErrorDomain Code=4097 "connection to service named com.apple.AuthenticationServicesCore.AuthenticationServicesAgent" UserInfo={NSDebugDescription=connection to service named com.apple.AuthenticationServicesCore.AuthenticationServicesAgent}
What can be the potential reason?
Did you find a solution? I have the same issue
I had this same error, but it was caused by switching to a different webauthn library in the backend server. The new library encodes things slightly differently which I think doesn't play nicely with AuthenticationServices.
Some updates- url safe encoding (using - and _ and no padding) causes this issue, fixed by replacing unsupported characters and adding padding.
Thanks. This helped solve my issue. Today I learned that there is regular base64 and URL-safe base64. This answer on StackOverflow details the differences between the two nicely: https://stackoverflow.com/a/55389212
I originally passed a URL-safe base64 string into createCredentialRegistrationRequestWithChallenge, which caused this error to occur. After converting it into regular base64, the issue was resolved.
