I think we should add this to Issue widgets in dashboards too since it's a valid query filter. You can make that change in static/app/views/dashboards/widgetBuilder/issueWidget/fields.tsx. Just gotta add a field key entry and put it in the ISSUE_FIELDS object with a boolean type.

ISSUE_FIELDS

I didn't know about this class, nice, but there's no other error.something property, I'd be expecting all the others there too, ideas why?
I'll merge this to unblock this feature but I can do it in a separate PR if we want to go ahead.

Good point, there are a lot of fields that aren't available there as columns. I recall now that we made an explicit choice to keep the column selections limited to a small subset but I'll have to follow up with why and what conditions mean we should add it to the column selector
