Hi,
This is an error which we get in Elasticsearch when trying to index geo_shape
fields but it seems this can be narrowed down to a problem in Lucene. We can
reproduce the problem withe ES 6.8.x and ES 7.7.x. This is the error we are
getting:

This is a very basic geometry. Could someone please explain why this shape is
invalid?
