Try Execute bench update --patch

You mostly get this problem, because there are differences in database schema between version 13 and v14…, So you are getting an error when performing a “migration”…

Maybe I can’t help, but I’m sure there are some solutions to this problem…

  • Maybe the upgrade patch can handle data migration (by executing patch files).
    Or: Anyway…
  • You can export data from the old site to the new site, perform a manual data migration… :innocent:
