Seafile 9.0.4 Twilio 2FA error when trying to enable under user preference

When I select Settings, Two-Factor Authentication then select “Enable Two-Factor Authentication” the following page loads with radio buttons “Token Generator” and “Text message”. But when I click the next button I get the following error.

AttributeError at /profile/two_factor_authentication/setup/

Im unable to get any further than this.

Any Ideas or can you point me in correct direction?
