Data Browser does not allow to access a table because of the following message. But as you can see the column “monthlyCohortNumber” does exist. And there are 4 records in that table. I tried to delete this column, but without any success. Please advise, I am running out of ideas.
I can not say anything definitely without deeper investigation.
But i can suggests the the server fix error automatically. (some simple inconsistency errors may be fixed on the fly).
