updateData throws exception when called on source with dynamic=true and cluster=true

[athoma13]

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

1. Create a GeoJSON source with dynamic=true AND cluster=true
2. 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))
