I've recently upgraded to Apex 26.1 (from 24.1). I've been using the Working Copy feature since the outset for my applications but am now getting this error when performing WC updates (Merge, Refresh, Compare, etc..) which effectively renders this feature unusable right now. This is the same on both pre- and post- upgrade WCs.
1 error has occurred
- ORA-06502: PL/SQL: numeric or value error: character string buffer too small
Any thoughts, team?
