Description
Hi,
I am trying to use updateData on a GeoJSON source that has both dynamic=true and cluster=true.
An exception is throw, and I cannot use updateData.
mapbox-gl-js version: 3.5.2
browser: chrome 127.0.6533.74
Steps to Trigger Behavior
- Create a GeoJSON source with dynamic=true AND cluster=true
- Once the map is loaded, try adding a feature to the source map using updateData
Link to Demonstration
https://stackblitz.com/edit/mapbox-cluster-and-dynamic-bug?file=main.js
- See errors in the console when clicking the 'Add Location' button
- Set cluster=false, and 'Add Location' will add points around (0,0) on the map.
Expected Behavior
I should be allowed to call updateData on a source that has both cluster=true and dynamic=true, or at least an exception that makes sense if setting both flags simultaneously isn't allowed.
Actual Behavior
Exception has occurred: TypeError: undefined is not iterable (cannot read property Symbol(Symbol.iterator))
at $.load (blob:...)
at blob:...
at _e.loadGeoJSON (blob:...)
at _e.loadData (blob:...)

Research direction
Start with the main.js reproduction in the linked StackBlitz project and run it with mapbox-gl-js 3.5.2. Trace the updateData call after the map loads when the GeoJSON source uses both dynamic=true and cluster=true. Done means adding a point no longer throws the reported TypeError, or the API reports a clear error for the unsupported combination.
