Nextcloud provided the following link to fix this issue, but since this is Nextcloud running on Nethserver I would prefer I get direction from Nethserver Support on how best to remove this error.

Thank you.

Hi Team,

I’ve discovered that the error is with the App Passman and the fix is with them. I will remove this app for now until it is fixed.

I will now resolve this post.

Thank you.
