I have updated the code. I noticed the "isLeftValue" and "isRightValue" are only initialized inside an 'if', that may not be entered by the code based on the 'if' condition. Putting the variable initialization outside the 'if' should work.   // This rule will calculate the left and right municipality for a road. // It determines if the road is completely within a intersectingArea or falls on the edge of a intersectingArea and updates the appropriate values on the road // Define the Road Centerline fields var jurisleft_field = "L_JURISDIC"; var jurisright_field = "R_JURISDIC"; // Define the Geopolitical Areas fields var jurisname_field = "JURISD"; // Get the intersecting Geopolictical Areas var intersectingAreas = Intersects(FeatureSetByName($datastore, "PublicSafetyGIS_Data.PUBLICSAFETYGIS.Test_Jurisdictions", [jurisname_field], true), $feature) // This function will convert a polygon geometry to a polyline function polygonToPolyline(p) { var json = Dictionary(Text(p)); var polylineJSON = { "paths": json["rings"], "spatialReference": json["spatialReference"] }; return Polyline(polylineJSON) } // Test if the road falls completely within a area and does not overlap any of the area's outline // If it does update the left and right value to be equal to the area's value var isWithin = false; var partialOverlap = []; for (var intersectingArea in intersectingAreas) { if (Within($feature, intersectingArea)) { var line = polygonToPolyline(Geometry(intersectingArea)); if (!Overlaps($feature, line)) { var jurisleft = intersectingArea[jurisname_field]; var jurisright = intersectingArea[jurisname_field]; isWithin = true; break; } // Store any boundaries the line is partially within (overlaps some of the polygons intersectingArea) else { Push(partialOverlap, intersectingArea); } } } // If the road does not fall within a area, attempt to find any areas that it overlaps the outline // Then test if the polygon is on the right or left side of the line and update the right or left value var isRightValue = false; var isLeftValue = false; if (!isWithin) { for (var intersectingArea in intersectingAreas) { var line = polygonToPolyline(Geometry(intersectingArea)); if (Within($feature, line)) { // Offset the geometry to the right and test if it intersects the intersectingArea var offset_geometry = Offset($feature, 5); if (Intersects(offset_geometry, intersectingArea)) { var jurisright = intersectingArea[jurisname_field]; isRightValue = true; } // Offset the geometry to the left and test if it intersects the intersectingArea offset_geometry = Offset($feature, -5); if (Intersects(offset_geometry, intersectingArea)) { var jurisleft = intersectingArea[jurisname_field]; isLeftValue = true; } } } } // If either the left or right value is not set we will loop through the partially within var jurisleft = "" var jurisright = "" if (isLeftValue || isRightValue) { for (var i in partialOverlap) { var intersectingArea = partialOverlap[i]; var line = polygonToPolyline(Geometry(intersectingArea)); // Get the portion of the road that overlaps the polygon intersectingArea var intersection_geometry = Intersection($feature, line); // Offset this portion of the road to the right and test if it intersects the intersectingArea var offset_geometry = Offset(intersection_geometry, 5); if (Intersects(offset_geometry, intersectingArea) && !isRightValue) { jurisright = intersectingArea[jurisname_field]; } // Offset this portion of the road to the left and test if it intersects the intersectingArea offset_geometry = Offset(intersection_geometry, -5); if (Intersects(offset_geometry, intersectingArea) && !isLeftValue) { jurisleft = intersectingArea[jurisname_field]; } } } return { "result": { "attributes": Dictionary( jurisleft_field, jurisleft, jurisright_field, jurisright ) } }     ...
