Scriptrunner JQL functions seem to not work

[Johan Pretorius]

JIRA gives me an error when I try to run this query:

project = BNM AND issuetype in (Bug, "User Story", "Technical task", "User Story Bug") AND subtasksOf(((status != Backlog AND Type = "User Story") OR type != "User Story"))

The error is as follows:

Error in the JQL Query: Expecting operator but got '('. The valid operators are '=', '!=', '<', '>', '<=', '>=', '~', '!~', 'IN', 'NOT IN', 'IS' and 'IS NOT'. (line 1, character 102)

We're running a downloadable JIRA (v6.1.6).  I've checked the add-ons page in the admin console and it indicates that Scriptrunner v2.1.16 is installed, 1 module is disabled: 

Resource to add View in Navigator to sprints on the rapid board (ghShowInNavigator)

What am I missing to get this to work?

Hey Johan.

• subtasksOf is used in combination with helper function issueFunction.
• You forgot quotes inside subtasksOf 
  

So it should look something like this 

project = BNM AND issuetype in (Bug, "User Story", "Technical task", "User Story Bug") AND issueFunction in subtasksOf('((status != Backlog AND Type = "User Story") OR type != "User Story")')

Thank you Andrey! This works perfectly now. I wish the documentation for scriptrunner would make this clear too, but at least now the answer is on here.
