Exterior Shell of polygon is invalid - 2dSphere Polygon

Question

Question, trying to index and getting the following error:

"Exterior shell of polygon is invalid"

However, I've tested the JSON on http://geojsonlint.com/ and it works

Here's my JSON

Answer 1

What version of mongodb are you running. If you are running 2.4, try upgrading to 2.6. I had the same error message with census tiger line data that I had converted to GeoJSON, and which I had also confirmed via jsonlint. I had been running the index on version 2.4. I upgraded to mongodb version 2.6, and that solved my problem. I was able to create a 2dsphere index and run geonear queries just fine after that.
