Invalid filter value: filter property must be a string

[bohdancorpsoft]

App crashes when I try to create a style layer with following filter:
[ "all", [ "!=", "cluster", true ], [ "has", "displayType" ], [ "==", "displayType", "map-marker" ] ]

Output from XCode:

Could you please try [ "all", [ "!=", "cluster", true ], [ "has", "displayType" ], [ "==", ["get", "displayType"], "map-marker" ] ] ?
Or if that does not work try to hunt down which sub-expression causes the issue by removing them one-by-one (e.g. test only [ "all", [ "!=", "cluster", true ], [ "has", "displayType" ] or [ "all", [ "has", "displayType" ], [ "==", "displayType", "map-marker" ] ] etc.)?
