I created an online map, then created a share link so my field crew could use it on their phones. The background layer comes up, but the shape files I uploaded do not. At the bottom of the phone screen we see the feature layer must be created with either a url or a source error. Any idea what might be happening here? Thanks
I know this was 1.5 years ago, but just in case anyone else comes across this -
I had this error come up when trying to use the Arcade FeatureSet function. It turns out it was because I was using a map image layer, rather than a feature layer. This might have been your same issue (ie. not using a feature layer).
I couldn't find anything about the error online, so hopefully this can inform others who run into it!
