TypeError exception is raised when attempting to login to multivisor using authentication

[bbugyi200]

My multivisor.conf file:

[global]
name=multivisor
username=test_user
password=test_password

[supervisor:A]
url=localhost:9051

[supervisor:B]
url=localhost:9052

Directly after hitting the "Log In" button on the multivisor site (after putting in my creds), nothing changes on the web console and I see this in the logs:

@tiagocoutinho,

Any plan to issue a point release with this bug fix?
Or maybe did you know if there is a workaround for enabling authentication without stumbling in this issue?

Exposing multivisor with no authentication is a blocker, unfortunately.

Thanks

Any news on this ?
