Additional Information

The issue is not reproducible. For cross-platform support, it is recommended to use an Arcade expression. When using an Arcade expression, the layer’s REST resources are displayed as follows: "labelingInfo": [ {"labelExpressionInfo": { "expression": "$feature.STATE_NAME + \" (\" + $feature.STATE_FIPS + \")\"", "title": "my expression" }}] When a Python expression is used, it is translated into a simpler form, as shown below. This is because Python expressions are not supported by web client apps. "labelingInfo": [ { "labelExpression": "CONCAT [STATE_NAME] CONCAT \"(\" CONCAT [STATE_FIPS] CONCAT \")\"" }]
