Inconsistency in automation condition check

Question

For automation conditions, why can I specify "is not empty" in a "Issue field condition" but not for a "Advanced compare condition"?

John Funk · Answer

Just choose equals and then leave the next field blank.

See how "Issue fields condition" has "is not empty" as an option but "Advanced compare condition" does not...

Hi Bryan,

Can you provide some more details? And even share your rule?
