Proper ESRI format for a JSON file

Question

I keep getting a 001558: Error parsing .json file. According to ESRI documentation for that error, "the JSON must have at least the geometryType, spatialReference, fields, and features (with geometry and attributes) property." I checked my .json file and it appeared to have all that but I want to see an example of a proper format. Can anyone give me a proper example of hwo ESRI want a file to look. Below is what my .json file looks like: {"displayFieldName": "CSLF_ID","fieldAliases": {...},"geometryType": "esriGeometryPolygon","spatialReference": { "wkid": 102100, "latestWkid": 3857},"fields": [...],"features": [ {"attributes": {...}, "geometry": {...} },...]}

If it was working up until yesterday, then I am at a loss for why is stopped working.  Did you install any new Esri software, patches, or updates?  Have you tried rebooting the machine?

The only difference that I can see in my JSON data is that the geometry comes after the attributes in features. But this was working up until yesterday.

I think An overview of the JSON toolset—Help | ArcGIS for Desktop is out of date.  I thought "fieldAliases" was deprecated back around 10.0.  Try removing that element and see if it works.
