FeatureLayer parameter outSR syntax

WillHughes — Sat, 11 Dec 2021 09:36:53 GMT

See Esri sample below. I am trying to output the geometries in lat/long 4326. Can someone check the syntax?

Basic Querying in FeatureLayer | ArcGIS API for JavaScript 4.16

See line 160.

outSR: "{wkid:4326}",

The output spatial reference is not going into the request.

Will,

There is no such property as "outSR" on the query class. You need to use the outSpatialReference property.

outSpatialReference: "4326", This syntax worked. Thanks!
