Hi,

I am using an action to execute a java script which extracts/import a zip to a location xyz. If the zip is corrupted i need to log the same in a log file.In the positive case it is working properly. But in the negative scenatio (if the zip is corrupted) the logging code is not working.

here is my code

var tempnodepath = "repository/temps";
var lognodepath = "repository/LOGS";
var lognode = companyhome.childByNamePath(lognodepath);
var tempnode = companyhome.childByNamePath(tempnodepath);
var errorlog = lognode.childByNamePath("error_log.txt");
if(errorlog == null || errorlog.length = 0){
   errorlog = lognode.createFile("error_log.txt");
}
// take the filename only, remove the extension
var tempfilename = document.properties.name.substring(0,document.properties.name.lastIndexOf("."));
// create the folder
var tempfolder = tempnode.createFolder(tempfilename);
// import the zip into the newly created "temp"
var extractor = actions.create("import");
extractor.parameters.destination = tempfolder.nodeRef;
extractor.parameters.encoding = "utf-8";
try{   
   extractor.execute(document);
   }catch(exception){
   errorlog.content = exception.message + "\r\n";
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

ps: I have configured a rule to execute the above script when a zip is added to the folder called uploads.

The execute() exception probably marks the whole transaction for rollback, so your error content never gets committed to the repository.

It's better to return an error HTTP response or, if that's not practical, at least raise an error in the logs.

Thanks,
