update data in portal hosted layer using rest end point

Question asked by on Oct 8, 2020

Hi Team,


I have to update gdb data in portal-> hosted feature layer using its item id. I got below rest end point to perform this.



While executing below code, I am getting an error --- {ERR_INVALID_ARG_TYPE] the first argument must be one of type string or buffer.

can any one please let me know how to resolve this or any change in passing inputs etc..


I am working on nodejs, but any other technology working sample also will help me to resolve this.


var options = 


   file:fs.createReadstream(<fPath of gdb/zip file>),





} {url:<url>,formData:options}, function(err, response,body){

   ------to do--------------



Thanks & Regards,
