• Operating System & Version: Ubuntu 22.04 (64-bit)

• Browser Type & Version: Chrome 133.0.6943.126 (Official Build) (64-bit)

• Rocket.Chat Version: 7.5.0

• Expected Behavior:
  When making a request to /api/v1/login with a custom OAuth token, the response should either be a successful login or an Unauthorized response if the token is invalid.

• Actual Behavior:
  Instead of the expected response, the API returns an Internal Server Error.

Steps to Reproduce:

1. Create a custom OAuth provider in Rocket.Chat.
2. Attempt to log in using the /api/v1/login endpoint with a valid OAuth token.
3. Observe that the response is an Internal Server Error.
