FeatureLayer.query() returns RuntimeError: Token Required (Error Code: 499)

Question

I am trying to query a FeatureLayer. I can connect to the GIS (using IWA), I validate the connection by checking the User, so I know the GIS object is valid. Create a FeatureLayer object using a valid Url (the FeatureLayer object is created). But when I run query I get RuntimeError: Token Required (Error Code: 499). See full stack trace below. Pretty simple code gis = GIS(portal, '', '') # IWA # get the webmap to use offline offline_map_item = gis.content.get(webmap) offline_webmap = WebMap(offline_map_item) featureLayer = FeatureLayer(projects_url, gis) features = featureLayer.query()‍‍‍‍‍‍‍‍ The issue is I see no way you would pass a token to this method. I passed the GIS object when initializing the FeatureLayer and the server is federated so I would think this passes the required tokens. Can some please help explain how I should be passing a token to this method from an IWA configured portal to a federated server in this call. Thanks -Joe Stack trace: RuntimeError Traceback (most recent call last) C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\__init__.py in _hydrate(self) 7577 -> 7578 self._refresh() 7579 C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\__init__.py in _refresh(self) 7544 else: -> 7545 dictdata = self._con.post(self.url, params, token=self._lazy_token) 7546 C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\_impl\connection.py in post(self, path, postdata, files, ssl, compress, is_retry, use_ordered_dict, add_token, verify_cert, token, try_json, out_folder, file_name, force_bytes, add_headers) 1155 -> 1156 self._handle_json_error(resp_json['error'], errorcode) 1157 return None C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\_impl\connection.py in _handle_json_error(self, error, errorcode) 1176 errormessage = errormessage + " (Error Code: " + str(errorcode) +")" -> 1177 raise RuntimeError(errormessage) 1178 RuntimeError: Token Required (Error Code: 499) During handling of the above exception, another exception occurred: RuntimeError Traceback (most recent call last) C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\__init__.py in _hydrate(self) 7586 self._lazy_token = None -> 7587 self._refresh() 7588 C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\__init__.py in _refresh(self) 7544 else: -> 7545 dictdata = self._con.post(self.url, params, token=self._lazy_token) 7546 C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\_impl\connection.py in post(self, path, postdata, files, ssl, compress, is_retry, use_ordered_dict, add_token, verify_cert, token, try_json, out_folder, file_name, force_bytes, add_headers) 1155 -> 1156 self._handle_json_error(resp_json['error'], errorcode) 1157 return None C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\_impl\connection.py in _handle_json_error(self, error, errorcode) 1176 errormessage = errormessage + " (Error Code: " + str(errorcode) +")" -> 1177 raise RuntimeError(errormessage) 1178 RuntimeError: Token Required (Error Code: 499) During handling of the above exception, another exception occurred: RuntimeError Traceback (most recent call last) <ipython-input-12-554803401d1a> in <module> 2 3 featureLayer = FeatureLayer(projects_url, gis) ----> 4 features = featureLayer.query() C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\features\layer.py in query(self, where, out_fields, time_filter, geometry_filter, return_geometry, return_count_only, return_ids_only, return_distinct_values, return_extent_only, group_by_fields_for_statistics, statistic_filter, result_offset, result_record_count, object_ids, distance, units, max_allowable_offset, out_sr, geometry_precision, gdb_version, order_by_fields, out_statistics, return_z, return_m, multipatch_option, quantization_parameters, return_centroid, return_all_records, result_type, historic_moment, sql_format, return_true_curves, return_exceeded_limit_features, **kwargs) 567 568 params['returnCountOnly'] = True --> 569 record_count = self._query(url, params) 570 if 'maxRecordCount' in self.properties: 571 max_records = self.properties['maxRecordCount'] C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\features\layer.py in _query(self, url, params) 1194 """ returns results of query """ 1195 result = self._con.post(path=url, -> 1196 postdata=params, token=self._token) 1197 if 'error' in result: 1198 raise ValueError(result) C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\__init__.py in _token(self) 7606 return self._lazy_token 7607 else: -> 7608 self._hydrate() 7609 return self._lazy_token 7610 C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\lib\site-packages\arcgis\gis\__init__.py in _hydrate(self) 7594 #

Hi Rohit,

I have the same issue. As you suggested, I use don't use username and password when connecting to my portal.

Interestingly, I only have this issue with hosted feature services (not shared, but I am the owner with administrator privilege), if the service is shared to everyone or not hosted, no issues.

so what's the possible cause?

Thanks.

Have you solved the problem when using IWA?

When using IWA, we don't provide the username and password altogether. The code should be gis = GIS(portal) # IWA instead of gis = GIS(portal, '', '') # IWA Can you confirm you're using the first way of connecting using IWA?
