Here is code added in App

  mapView.getMapboxMap().loadStyle(
               style(styleType) {
                   +geoJsonSource("current_location_id") {
                       geometry(getCurrentLocationCircle())
                   }
                   +layerAtPosition(
                       fillLayer("current_location_id", "current_location_id") {
                           fillOpacity(0.3)
                           fillColor("#e51500")
                       },
                   )
               }
           )

@arun-ns

1. can you reproduce this crash locally from your side?
2. could it be the case that it happens when style is switching from one to another?

[arun-ns]

We couldn't reproduce in locally. We got more than 10k crashes in Firebase Crashlytics @kiryldz

[wen-kai]

we're using rnmapbox which uses mapbox-maps-android under the hood and are also finding very frequent crashes in production. unfortunately the repro is inconsistent and seems to be some sort of race condition. it seems related to dynamic layers:

[orca-nazar]

@kiryldz Exactly, it happens when the style is switching. However, we use rnmapbox, so there is no way to provide a good example

[kiryldz]

@orca-nazar @wen-kai I assume you should then transfer this to rnmapbox repo...
@mfazekas - does this ring a bell perhaps?

[mfazekas]

@kiryldz the iconImage issue we have in @rnmapbox repo - rnmapbox/maps#2289 - was closed as no code to repro was posted there

[orca-nazar]

Thanks for the responses @kiryldz @mfazekas. After diving deeper into what the source/layer causes the issues on our app, I found a way to reproduce in rnmabox test app. Created a ticket with included all steps rnmapbox/maps#3152

[kiryldz]

Closing this one then.
