generateRegistrationOptions's `excludeCredentials` is returning empty string for each id

[rametta]

Describe the issue

When using generateRegistrationOptions and providing some array for excludeCredentials, the id's are provided as a UInt8Array to the function, but the return type from the function has all the id's inside the exlcudeCredentials array to be an empty string

Reproduction Steps

1. pass in an array for the excludeCredentials field in the generateRegistrationOptions, make sure every id is a UInt8Array type, like the library suggests
2. observe the return type of the function providing each id to be an empty string

Expected behavior

The return type of generateRegistrationOptions should have the excludeCredentials array have the id not be an empty string, and instead be the proper credential id

Never mind, I think the issue had to do with the way my cosmos db was serializing/deserializing the array buffer of credential id's
