I converted a feature layer to JSON format in ArcGIS Pro and I'm now attempting to upload the JSON file to My Content on AGOL as a hosted layer. Upon uploading (using Add Item-from my computer) an error appears ("Input string was not in a correct format. Couldn't store < > in TWD Column. Expected type is Int32.") The resulting attribute table is empty.
I thought there might be a field type mismatch in the field referenced in the error (TWD),. First I tried converting the field to an integer, but that didn't solve the problem. Then I removed the TWD field, but then the error recurred referencing another field. I'd appreciate any insights.
