So I came across this error when trying to get a list of the custom columns in all libraries - I need to see how many different instances I have of specific date columns.


calibre, version 3.44.0
ERROR: Unhandled exception: <b>SQLError</b>:SQLError: no such table: custom_columns

I deleted the bit about the third-party plugins.
