Check if Wiki type text field has only whitespaces

[Amit Kapoor]

Hi,

I am trying to find if my "CUSTOM_FIELD1" which is like JIRA's native Description field, did users add only whitespace in it and saved? Because whitespace is not treated as EMPTY, how do I find such issues that have one or more whitespace in the value and nothing else.

What JQL should I use? Please help!

I tried

"CUSTOME_FIELD1" ~ "\\' '"

Also,

"CUSTOME_FIELD1" ~ " "

Nothing works!!

Thank you!
