SymbolLayer filter property data type error; unable to pass filter array about maps HOT 7 CLOSED

It turns out in and '==',$type is legacy filter syntax, and it's no longer supported. Use the new expression syntax to get it work:

["all",
    ["==",["geometry-type"], "Point"],
    ["match",
       ["get", "type"],
       ["Blue Project", "WFW Project"], true,
        false]
]

"!has" is legacy filter syntax too use ["!", ["has" ...]

Bug was reported to upstream repo: mapbox/mapbox-gl-native#14805

from maps.

Would this issue hinder the EarthQuakes.js example from working? I tried to build it in the exact same way, but the app crashes everytime I launch...

Any idea how long this bug will take to fix?

I believe this issue also exists in SymbolLayer!

@lpfunding it seems that ios mapbox-gl-native have trouble with !has too - to be reported on upstream repo.

instead of

filter={['!has', 'point_count']}

you can try:

filter={['!', ['has', 'point_count']]}

from maps.

@systemlevel seems to be an upstream mapbox-native-gl / ios issue. The expression is converted to NSPredicate then back to mapbox expression.

[
                'all',
                ['==', '$type', 'Point'],
                ['in', 'type', 'Blue Project', 'WFW Project']
            ]

Becomes NSPredicate predicateWithMGLJSONObject

"$type" == "Point" AND MGL_FUNCTION("in", "type", "Blue Project", "WFW Project") == 1

Which becomes predicate mgl_jsonExpressionObject

[
                'all',
                ['==', '$type', 'Point'],
                ['==', ['in', 'type', 'Blue Project', 'WFW Project'], 1],
            ]

And then it fails to parse this expression.
