If we import the type Mesh instead of MeshAttributes I think we get this.

Used Mesh from @loaders.gl/schema as suggested. Typed it as Partial &
{ header: {vertexCount: number}; attributes: Mesh['attributes'] }
to keep schema, topology, and mode optional since the loaders.gl point cloud format doesn't require them, while sourcing the attributes type through Mesh rather than importing MeshAttributes separately.

header: {
vertexCount: number;
};
attributes: MeshAttributes;
};

const defaultProps: DefaultProps<PointCloudLayerProps> = {
sizeUnits: 'pixels',
pointSize: {type: 'number', min: 0, value: 10}, // point radius in pixels
