We’re having some problems with client tag datasets. The client tags are listed as “stale” and when trying to create new dataset tags I get an error “ClassCastException: Cannot coerce value ‘0’ into type: interface com.inductiveautomation.ignition.common.Dataset”.

Any ideas on what might be causing the issue?

I’m not sure if something was corrupted, or this was fixed in 7.3.1 but updating from 7.3.0 to 7.3.1 fixed the issue.

Indeed, it was a problem with 7.3.0 that was fixed in 7.3.1.
