__Problem__:
Warnings: [10], 'in function 'GEO_DISTANCE()': Invalid loop in polygon' Result: [ null ]

__Expected result__:
It should return valid distance between point and central point of area, returns null.
Result: [ {distance} ]

I think the polygon loop is actually invalid, the first and last edges are crossing. Change "50.098339840861776" -> "50.097639840861776" and it works

I made a PR to pass through the validation errors to the client

Thank you for your answer, it works :)
