Hi @ishaan-jaff Would this be an expected behavior? The app returns a 500 Internal Server Error for unauthorized routes when using custom_auth.

Example usage:

    allowed_routes = list(LiteLLMRoutes.llm_api_routes.value + LiteLLMRoutes.info_routes.value)
    
    user_api_key_auth = UserAPIKeyAuth(
        api_key="dummy",
        key_alias="alias",
        rpm_limit_per_model=rpms,
        tpm_limit_per_model=tpms,
        models=[],
        allowed_routes=allowed_routes
    )

message=f"Virtual key is not allowed to call this route. Only allowed to call routes: {valid_token.allowed_routes}. Tried to call route: {route}",
type="auth_error",
param="api_key",
code=403,
