ArcGIS Field Maps cannot load geojson layer from URL

ESRI_User_121

So I'm trying to load a geojson file from this url https://felt.nsdi.workers.dev/ and it's working on ArcGIS Online. But when I'm trying to view it from Field Maps app it says

Domain: com.esri.arcgis.runtime.error

Code: 7005

Description: Layer type is not supported

Any idea why the issue is occurring? It's 2025 and loading geojson from url should be very basic function in ArcGIS Field Maps.

Good afternoon. Geojson files are not supported in ArcGIS Field Maps. You can read more about data requirements here. With that being said, you can publish your geojson as a feature service and then view it in ArcGIS Field Maps.
