Using FEEL list contains(list, element) function in gateway connectors

Hi !
I try to use list contains() function in gateway connectors condition expression. Need your advise.
The source data is like this:

var1=
{
 "documentDate":"2025-05-28",
 "executors":[{"executor":"1111111"},
 {"executor":"2222222", "mainExecutor":"1"},
 {"executor":"3333333"}]
}

When I try to make a condition expression like:
list contains(var1.executors.mainExecutor, "1")
it works fine.

But I can’t make working expression with more complex condition like:
list contains(var1.executors, {"executor":"2222222", "mainExecutor":"1"})
Could you help me, please ?

You could achieve what you are attempting by using the list filtering capabilities of FEEL and then checking if the returned list is empty or not. There might be a way to make “list contains” work as well but this is the first idea I had. Here’s an example:

Thank you, Vasil for your help. It looks like this is the right direction. But I can’t check your advise right now because Camunda 8.5, I’m using, don’t know about is empty() function.
I’ll think a lot and write my decision if I’ll find. Any other cool ideas - welcome ! :slight_smile:
