[Hubspot API] How do you use IN filter operator?

Teun,

It seems that your last example doesn’t work for me, I am getting this error:

{"status":"error","message":"Invalid input JSON on line 9, column 17: Cannot construct instance of com.hubspot.inbounddb.publicobject.core.v3.search.Filter, problem: operator IN requires values","correlationId":"c0f97d27-fd9c-4e21-a476-ed9ee20a2000"}

This is what I have in Postman. Any input would highly be appreciated. Thank you.
