Hi,
I am getting this logging on my element when I try to do a history set. The code works like this:
1. Do an exists check on the key on the table
2. If it does not exist => Add row to the table, else => set row to the table using the key
The error only occurs sometimes. It runs in an instanced QAction.

Any ideas how this error may occur?
Hi Joshua,
This kind of error typically points to a race condition or a timing issue during concurrent access or modification of a table row. For example, if multiple QAction instances are triggered at the same time, one might create a row while another tries to delete or access it, leading to conflicts.
Have you had a chance to check for potential concurrency issues like that?
Hi Nejra,
Thanks for the suggestion. There are no static or queued QActions that are making concurrent writes to/deletes from the table.
