We are working on improving the feedback in these cases. The problem is that your Polygon has a self-intersection at lat=-1.6207097957553944, lon=103.58787259994486.

Wow, thanks. BTW, how do you find this point? Is there any method to fix it?

I just merged this change in Lucene that provides that information:

https://issues.apache.org/jira/browse/LUCENE-9538

Elasticsearch does not have the functionality to correct those kind of polygons at the moment.

Thanks.
We solved this issue in google map by formatting it in advance.
