JQL to find empty custom number fields

[Richard Cross]

We have projects using a custom (number) field to store Story Points.

Is there a JQL that will list only the issues that have no value for that field?

I've tried the following, but they simply return all issues:

"Story Points" = null

"Story Points" IS EMPTY

Hello,

"Story Points" is EMPTY should work.
