How to load a live GeoJSON URL in WebMaps
HI brains trust. I'm hoping someone can help me here. I've been reading all the literature, googling, etc and not getting far. I have a GeoJSON URL from tracertrak that shows the Last Known Location data for a tracking system. When I view the URL in the browser, I see the JSON data as expected.
I followed the Esri instruction to publish a GeoJSON as a hosted layer, which generated a JSON file in ArcGIS Online and a hosted layer showing the data, but it's static once published. I then found more instructions that said to load it directly into the WebMap and add a refresh interval, but when I do this, it adds as a table with no attributes and no data (or any other properties).
What am I missing?
I also used the Add Data function in Experience Builder to add it to a map and it loaded fine, but obviously this is temporary and can't be customised, so not overly useful (just dots on a screen with popups).
