I could use this fix. Running into the same issue. Can you assign this pull request to one of the contributors to get it moving?

I tested the feasibility of this fix by manually changing my sqlite3 table column to a String (from Int), but I still encountered the same problem. ☹️ I would probably next look at the code that parses the value from the 'placeholder' table to see if there's anything there that's attempting to treat the value as an Integer. Thanks for putting up this PR, at least -- helpful.
