ArcGIS JavaScript v3.17 - Spatial query to find out how many line features intersect polygon feature - arcgis-js-api

Question

I am working on a tool using ArcGIS JavaScript v3.17 to perform a spatial query to find out how many line features intersect a polygon layer. The process works for 1 polygon layers but does not work for the other 3 polygon layers (results in an error). The error I get is: "SyntaxError: Unexpected token <" when the query is ran, which doesn't tell me much about what is wrong. See sample code below. Has anyone else seen this before? Any suggestions or help would be greatly appreciated.
function submit() {
$('#submit').on('click', function () {
query;
});
}
function query() {
var polys = map.getLayer('lyr1');
var lines = map.getLayer('lyr2');
var queryTask = new QueryTask(lines.url);
var query = new Query();
query.geometry = polys.graphics[0].geometry;
query.spatialRelationship = esri.tasks.Query.SPATIAL_REL_INTERSECTS;
query.outFields = ['*'];
queryTask.on("complete", queryTaskExecuteCompleteHandler);
queryTask.on("error", queryTaskErrorHandler);
queryTask.execute(query);
}
function queryTaskExecuteCompleteHandler(queryResults) {
console.log("complete", queryResults.featureSet.features.length);
}
function queryTaskErrorHandler(queryError){
console.log("error", queryError.error);
}

I have solved my issue by going a different route and am now using the geometryEngine intersects process to find out if a line intersects a polygon. This involves a for loop that goes over a list of each line graphic > runs the intersects process comparing the polygon feature to the line graphic geometry > if true, the id gets pushed to an array > will use that array to get a total and also a definition expression on the line features.
