The REST API shows the following example to query:
"where" : "NAME LIKE 'A%'"
I'm trying to only label features with values.
I've tried to update the definition of the service and the specific feature layer with: "where" : "NAME is not null" . But the labels disappear completely.
I've also tried to use the the example esri provides: "where" : "NAME LIKE 'A%'"
However, something happens in the background to encode the value: "where":"NAME LIKE \u0027A%\u0027"
How do I set labelingInfo where:"Field is not null" ?
