Updating word lists with talon.cron can cause RuntimeError: dictionary changed size during iteration

I haven't tried to make a minimal test case but was asked to file, so here's what I know :)

Example trace:

Deep in my cron callback I was doing:

self.ctx.lists[f"user.{self.name}_list"] = data.keys()

Which curiously seems mitigated by (haven't had it happen since):

self.ctx.lists[f"user.{self.name}_list"] = list(data.keys())

Please try the issue again in the beta 105-0.1.2-54

I think this has been fixed for a bit, can you try to repro it on the latest beta?

[lunixbochs]

I do think this is fixed, please reopen if you can repro on beta

Sorry for not commenting earlier, since updating I have not seen this error happen again 👍 thanks!
