So I’ve got a power table in a window with a few editable columns. Whenever these columns are edited or changed, this error pops up ![](https://us1.discourse-cdn.com/inductiveautomation/original/2X/8/8c5485c857dbadff64e7d882a1c781a0445b1c54.PNG)

This was working fine before and just randomly starting giving this error. The power table updates anyway when it returns this error.

What version of Ignition are you using? This looks like an issue in 7.9.7/7.9.8, fixed in 7.9.9.
