Invalid Grant/Invalid id_token when authenticating with TouchID and Auth0

Hi all,
I’m having a hard time authenticating users with TouchID and Auth0. I get a 400 status code and the following error after the public key and the JWT token are successfully generated and when I try to login with the returned JWT.

    "error": "invalid_grant",
    "error_description":  "invalid id_token"

Any hint or suggestion?
