$root.users.confirmUserSettingsDialog is not a function when editing access control options for a user

[javawizard]

What were you doing?

Trying to make a non-admin user an admin. Go to Settings -> Access Control, click the edit button next to a user, then click Confirm. Happens whether or not you actually change either of the checkboxes.

What did you expect to happen?

Access control settings for the user to update, dialog to go away.

What happened instead?

Dialog stays, nothing changes, and I get VM877:3 Uncaught TypeError: $root.users.confirmUserSettingsDialog is not a function on the javascript console

Working on it, though probably not relevant.

Minified, so probably less than helpful, but here's the stack trace anyway.

I have read the FAQ.

Thanks for spotting this (and the full bug report that made it extremely easy to fix this one). Has been solved in maintenance and devel branch and will be part of the next release.

In the meantime, anyone who runs into this can solve the problem for now by editing ~/.octoprint/users.yaml and adding admin to the roles of a user and then restarting the server, e.g. turning

test:
  roles:
  - user

into

test:
  roles:
  - user
  - admin

in order to give admin rights to the user test. Only a workaround until the fix is released, but should solve any issues for now hopefully.
