If you cannot share then would you mind sharing json for one feature from your geojson file?&nbsp;</P> Mon, 05 Dec 2022 19:59:53 GMT UndralBatsukh 2022-12-05T19:59:53Z https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/geojson-attributes-are-undefined/m-p/1237562#M79544 <P>I have a geojson url that I am able to see features on the map. I can use a definition query towards it, but I cannot access the values. The data comes in as undefined, though I can see the count of the features. The data comes in as:&nbsp;(36)&nbsp;[u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u, u] in the console. I'm not sure how to extract the values from a geojson link.</P><BLOCKQUOTE><DIV>&nbsp;</DIV></BLOCKQUOTE><P>&nbsp;</P><LI-CODE lang="javascript">const query = geoJSONLayer.createQuery().set({ outFields: ["Category"], returnGeometry: true }); console.log(query) const { features, fields } = await geoJSONLayer.queryFeatures(query); console.log(features.attributes) let sel = document.getElementById("sel").innerHTML = ""; // Populate dropdown with list of provinces let dropdown = document.getElementById('locality-dropdown'); dropdown.length = 0; let defaultOption = document.createElement('option'); defaultOption.text = 'Choose State/Province'; dropdown.add(defaultOption); dropdown.selectedIndex = 0; const url = mygeojsonurl; fetch(url) .then( function (response) { if (response.status !== 200) { console.warn('Looks like there was a problem.
