Column not accessible

Incident
Columns don't show up in your spreadsheet template configuration, instead an error appears stating the column is not accessible.

Cause
The affected column was deleted in the board or you lack permissions. In some cases, when the column is a connect board or a mirror column, they don't show up because of a current bug in the monday API. In this case the API does not return these columns and to our app it then looks like they don't exist. This bug is impacting a few of our users, but also the users of other monday apps.

Solution
Check if you have permissions to access the column. In case of a mirror column, you may want to wait 1 to 2 days after creating your template and check if they then show up. We also created a ticket (#4304752) in the monday bug tracker for the "inaccessible mirror columns" issue on 4th of November 2025. The technical support has passed it on to the developers team at monday. We are now waiting for a fix which will hopefully happen soon, but we can't give an ETA (it depends on how monday prioritizes the issue).
