How to get returnCentroid to work when querying Feature Service layer

KarenRobine1

According to the documentation here: 

https://developers.arcgis.com/rest/services-reference/query-feature-service-layer-.htm 

There's a parameter, returnCentroid. According to the documentation Notes:

Note:

The layer metadata returns supportsReturningGeometryCentroid in the advancedQueryCapabilities metadata object. The absence of the supportsReturningGeometryCentroid property means that the server does not support the returnCentroid parameter. Line and point data will return supportReturningGeometryCentroid as false.

Question: I'm trying to figure out how to make the server support the returnCentroid parameter, because in our case, the supportsReturningGeometryCentroid property does not exist. FYI: We're on 10.8 so I know this is supposed to be supported in our version.

so re-reading the documentation on this. Turns out it's not possible on my linear data... ugh..

Used to return the geometry centroid associated with each feature returned. If true, the result includes the geometry centroid. The default is false. Currently, this parameter is not supported for polygon data and is ignored for count and objectID queries. This parameter is only supported on layer-level queries.

Note:

The layer metadata returns supportsReturningGeometryCentroid in the advancedQueryCapabilities metadata object. The absence of the supportsReturningGeometryCentroid property means that the server does not support the returnCentroid parameter. Line and point data will return supportReturningGeometryCentroid as false.
