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))
  at $.load (blob:...)
    at blob:...

Apologies for a confusing error message. The dynamic mode isn't designed to be used together with clustering, since the latter's algorithm requires reclustering the whole dataset on any change, so it can't take advantage of optimizations intended for non-clustering dynamic use cases. We'll add a meaningful error, but as a workaround, please use dynamic: false and setData instead.
