Feature Layer will not refresh ArcGIS Javascript API

Question

I am trying to integrate live point data (worker locations) from Workforce for ArcGIS into a Javascript web app that I am building.

The layer loads fine and displays on the map properly, it even refreshes as soon as I zoom in or out, but it does not refresh automatically no matter what I try. I have tried using .refreshInterval and when I log the FeatureLayer it has the property set correctly but no refresh happens.

 esriId.registerToken({
 server: 'https://www.arcgis.com/sharing/rest',
 token: sessionStorage.getItem('token'),
 userId: sessionStorage.getItem('user')
 });
 var portal = new Portal({
 authMode: 'immediate'
 });
 portal.load().then(function() {
 var query = {
 query: 'title:workers_ AND access:shared AND type:Feature Service'
 }
 portal.queryItems(query).then(function(queryResult) {
 workers = new FeatureLayer({
 title: 'Workers',
 refreshInterval: 0.1,
 portalItem: queryResult.results[0]
 });
 workers.when(function() {
 workers.makeTemplate();
 console.log(workers);
 });
 map.add(workers);
 });
 });

I have also tried using

setInterval(function() {
 workers.refresh();
 console.log('hi');
}, 6000);

This logs hi every time but still does not refresh the layer. There are no errors of any kind in the console either. I have tried in both most recent Chrome and most recent Edge.

Does anyone know what the problem is/how to fix it?

• Mintx: Have you tried using a StreamLayer instead of a FeatureLayer?

Answer 1

This is a bug in the 4.9 JS API. It is in the queue for fixing in 4.10. We failed to implement refresh() using our WebGL-rendered FeatureLayer. It still works if you disable WebGL, but I don't recommend that approach since we plan to only support WebGL rendering in the future. This was oversight on our part, and we plan to resolve it shortly. Sorry about that.
