Instance members of Source doesn't have a type definition.

https://maplibre.org/maplibre-gl-js-docs/api/sources/#geojsonsource-instance-members

Property 'getClusterExpansionZoom' does not exist on type 'Source'.
Property 'getClusterChildren' does not exist on type 'Source'.
Property 'getClusterLeaves' does not exist on type 'Source'.
Property 'setData' does not exist on type 'Source'.

and this causes a TypeScript compiler error.

Please cast source to geojsonsource.

Ok, I could cast to any too xD.
Are you planning to fix this signature? thx

The source that is returned can be any source , geojson, vector, image etc.
You need to cast it to the relevant type.
Casting to any won't allow you auto complete...
