@mayank250004 can you provide the KML file you used?

@mayank250004 can you provide the KML file you used?

@barbeau you can download kml file using the following link via google drive

@barbeau did you check kml file?

any update!

[barbeau]

Not at this point, but I hope to have more time to dedicate to this project in the near future.

@barbeau please look if you can
I am stuck in my project because of this issue

[barbeau]

Based on the stacktrace and looking at the KML file, I'm guessing this empty tag is causing the issue:

<hotSpot />

As a workaround can you please try deleting this from the KML file and see if it loads then?

[mayank250004]

@barbeau thanks a lot

after deleting tag now kml loads successfully

I am wondering why google not handling this in their code
