When ArcGIS Experience Builder is connected to ArcGIS Enterprise 11.1, the GeoJSON file exported from the selected feature and the Table widget cannot be added to ArcGIS Online or ArcGIS Pro.

The underlying issue seems to be that the exported GeoJSON file includes geometries in a projected coordinate system, however, the coordinate reference system (CRS) is not included in the output so ArcGIS clients (Pro/Online/etc.) assume it is in WGS84 and that causes the failure. A workaround is to open the exported GeoJSON file, manually add the correct coordinate reference system (CRS) information into the file.
