I added layer to existing feature layer using "addToDefination" API. 

Input layer data : http://jsonblob.com/1234911840365830144. even if giving name of field is "fid" still taking "fid0" after adding. 

API used : https://{{Domain}}/arcgis/rest/admin/services/Hosted/First_Upload/FeatureServer/addToDefinition?f=json&token={Token}

With this layer get added to feature layer. but can't see layer on viewer because item data is missing. I am trying to add item data using shape file "Append content" option. It throwing error. I did mapping of field also. Not sure whats wrong. 

 

 

First_upload.zip is which I uploaded initial layer which become feature layer. In that using addTodefination API I added second layer with similar defination of second_upload.zip. After adding layer try to upload second_uploadz.zip file using append to layer for second layer.
