Find formulas (or errors) in hidden tabs

I have a shared workbook of weekly reports which has over 30 hidden tabs. Tabs are hidden so that only the current week's data is visible and the following week, that tab would get hidden and next week's tab would be visible and so on.

Recently I've come across a message that there is a formula error somewhere in the workbook (see screenshot).

How can i find which page has a formula / error in a workbook that has hidden tabs please, without having to 'unhide' every single tab?

thank you
