issues with ProjectRoles and fast-track transition

[Kiril Kolev]

Hi guys, 
I'm trying to use this script, but I get an syntax error, even though I followed the recommended instructions (https://docs.adaptavist.com/sr4jc/latest/features/workflow-extensions/jira-expression-examples -> user.getProjectRoles(project).some(p => p.name == "userrole")), using ID instead of NAME, but its the same result. Any help is appreciated:

I'm trying to create a Post Function on a transition of type "Fast-track transition issue".

Thank you in advance

Script: user.getProjectRoles(project).some(role => role.id == proper_id)

Error

Unexpected input: '(project).some(role =>' @ line 1, column 42.
   jectRoles(project).some(role => role.id 
                                 ^
