I am trying to update a apex class in salesforce by using metadata api but recieving this error when I call the update_x method.
I have achieved to get the zip file package of the desired class and unzipped it by using JSZip, now when I try to update the whole package it gives me the error.
Also I have red it on the net that you have to get the zip back together to save the results successfully, but I am not sure how to again make a zip of the class, class-meta and package.xml files.
