@User error handling has changed from how it used to work.. If you follow the backend quick setup guide, you will see that you need to add supertokens' errorHandler (https://supertokens.io/docs/emailpassword/quick-setup/backend#4-add-the-supertokens-error-handler). This in turn implies that you no longer have to manually handle

UNAUTHORISED

or

TRY_REFRESH_TOKEN

in your error handler.
