Facing TypeError: unsupported operand type(s) for -: 'list' and 'frozenset'

Was running elastalert with python3.13 elastalert 2.26, whihc was runnning fine for the longest time, i make a change to the code of one rule and suddenly it starts throwing out this error:
`

two changes were just added:

1. a filter to the rule, nothing that would cause this to happen and
2. changed the name of the custom rule file

however after disabling the rule and running the rest, still faced this error......can someone explain what happened, no elastalert or python update was done by me. and this is running in a pyvenv.

Thanks!

an update: the rule that I changed is being run in the same py venv in another terminal as well and it is working fine, i have restarted that elastalert as well. very strange behavior

I'm not clear on the situation. Based on your latest update, it sounds like it works fine in one terminal, but not in another?

figured it out, it was due to a change in a custom rule, where it was not showing up as the script was already running but once I restarted it, and tested all rules using elastalert-test-rule it clearly showed up
