Issue with ArcGIS API for Python Append Function in AGOL Notebooks Beta

Question

Hi all, Wondering if anybody else had this issue: when using the append function from the python API, I receive an "Object reference not set to an instance of an object" error. The weird part is I've gotten the code to work previously after getting the error, then today went I went in to make some adjustments, it stopped working all the sudden. The previous reason I was getting the error had to do with the field names not matching, but that has since been corrected (since I'm appending from a shapefile, I had to account for truncated field names). While troubleshooting, I used the exact same code from within the python window in ArcGIS Pro and it appeared to work, which makes me think something else is going on here. Here is the code in question: # get public lease feature layer public_leases = gis.content.get('item id string') # get specific sublayer from public lease feature layer public_lease_layer = public_leases.layers[0] # get source lease data source_leases = gis.content.get('item id string') # get source lease layer source_leases_layer = source_leases.layers[0] # Query for only Active, Pending Leases as a spatial data frame source_leases_query = source_leases_layer.query(where="RecordStatus = 'Active' Or RecordStatus = 'Pending'").sdf # Publish the spatial data frame as a feature layer, will also publish a shapefile temp_layer = source_leases_query.spatial.to_featurelayer('temp_lease_feature_layer') # Export temporary layer to shapefile temp = temp_layer.export('temp_lease_shapefile','Shapefile') # append public lease layer with records from temp shapefile (SLC Properties) using upsert public_lease_layer.append( item_id=temp.id, upload_format='shapefile', upsert=True, update_geometry=True, use_globalids=True, field_mappings=[ { 'name': 'RecordStatus', 'source' : 'RecordStat'}, { 'name': 'LeaseNum', 'source' : 'LeaseNum'}, { 'name': 'GeneralLocation', 'source' : 'GeneralLoc'}, { 'name': 'LeaseorPermit', 'source' : 'LeaseorPer'}, { 'name': 'TypeofLease', 'source' : 'TypeofLeas'}, { 'name': 'LeaseStartDate', 'source' : 'LeaseStart'}, { 'name': 'LeaseExpirationDate', 'source' : 'LeaseExpir'}, { 'name': 'SLCApprovalDate', 'source' : 'SLCApprova'}, { 'name': 'MinuteItem', 'source' : 'MinuteItem'}, { 'name': 'Improvements', 'source' : 'Improvemen'}, { 'name': 'Latitude', 'source' : 'Latitude'}, { 'name': 'Longitude', 'source' : 'Longitude'}])‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ And here is the error I get: --------------------------------------------------------------------------- RuntimeError Traceback (most recent call last) <ipython-input-13-93b5922cf27b> in <module> 43 { 44 'name': 'Longitude', ---> 45 'source' : 'Longitude'}]) /opt/conda/lib/python3.6/site-packages/arcgis/features/layer.py in append(self, item_id, upload_format, source_table_name, field_mappings, edits, source_info, upsert, skip_updates, use_globalids, update_geometry, append_fields, rollback, skip_inserts, upsert_matching_field) 1456 sres = self._con.get(path=surl, params={'f' : 'json'}) 1457 while sres['status'].lower() != "completed": -> 1458 sres = self._con.get(path=surl, params={'f' : 'json'}) 1459 if sres['status'].lower() in "failed": 1460 break /opt/conda/lib/python3.6/site-packages/arcgis/_impl/connection.py in get(self, path, params, ssl, compress, try_json, is_retry, use_ordered_dict, out_folder, file_name, force_bytes, add_token, token) 900 return self.get(path=path, params=params, ssl=True, compress=compress, try_json=try_json, is_retry=True) 901 --> 902 self._handle_json_error(resp_json['error'], errorcode) 903 return None 904 except AttributeError: /opt/conda/lib/python3.6/site-packages/arcgis/_impl/connection.py in _handle_json_error(self, error, errorcode) 1201 1202 errormessage = errormessage + " (Error Code: " + str(errorcode) +")" -> 1203 raise RuntimeError(errormessage) 1204 1205 class _StrictURLopener(request.FancyURLopener): RuntimeError: Object reference not set to an instance of an object.

This is insane. I have been dealing with the same thing for hours with the same error. My code is very similar to yours and I have it working perfectly on desktop with a file geodatabase from a dataframe query. Does it like the exact same code on an AGOL notebook? Of course not.

In addition, I can't even get it to append from a feature layer collection anywhere. The documentation says it is an option, but I have never seen anyone do it before. You didn't by any chance get this figured out in the last year?
