Goals

Be able to distinguish authentication errors by their code.

Expected Results

Have a unique error code for every error message.

Actual Results

When logging in realm with a JWT token, I can receive the following error codes (among others):

{code:46, message: "user disabled"}
{code:47, message: "(something about authentication failed...) ; token is expired"}
{code:47, message: "failed to lookup key for kid=..."}

The last one occurs when I try to log in my production realm with a staging JWT, for instance.

It doesn't seem logic to me to have the same error code for two different errors, especially since my app should behave differently in case I get a 47 error code:

• "failed to lookup..." => logout, clear token cache
• "token expired" => renew token, then retry to log in Realm
