When marking assets by python api, the icon does not show properly in the asset browser can not see the thumbnail. But I can mark the asset.

       obj = bpy.data.objects["dishwasher1"]  
       obj.asset_clear()
       obj.asset_mark()

Any one can help on this?

Let's have a look at what Python Console suggests with autocomplete:

object.asset_generate_preview() looks interesting.

    $\begingroup$ Note the generation is asynchronous so you won't be able to access the image data directly after calling asset_generate_preview but you can use application timers to wait for a bit for the preview to render. $\endgroup$
