Task lambda_package create empty zip

[Jérôme Heissler]

I try to run the task on my iMac the generated zip doesn't contain any sources.

I added this piece of code to see files that are added to the archive. And I see nothing.

zipArchive.on('entry', function(data)   {
  console.log(data);
 });

Next I change the install_location to a directory on the project root, all the files to be compressed are listed correctly. But the archive is corrupt.

var install_location = "./.tmp";

Finally I changed the script that copies the archive to wait for the copy before deleting, and everything works.

output.on('close', function () {
  mkdirp('./' + options.dist_folder, function (err) {
    fs.createReadStream(install_location + '/' + archive_name + '.zip').pipe(
      fs.createWriteStream('./' + options.dist_folder + '/' + archive_name + '.zip')
    ).on('close', function(){
      rimraf(install_location, function () {
        grunt.config.set('lambda_deploy.' + task.target + '.package',
            './' + options.dist_folder + '/' + archive_name + '.zip');
        grunt.log.writeln('Created package at ' + options.dist_folder + '/' + archive_name + '.zip');
        done(true);
      });
    });
  });
});

I'm a beginner with node js and grunt, there is there a problem in my configuration or worries with the task ?

Hi @jeromeheissler

Is it at all possible to post a link to your code so I can try and run it myself? Even if just an example that prints "Hello World" or something but still exhibits the issue?

Also, it might be useful to try a basic example using the archiver package to see if the NPM package itself is the issue or just this implementation using it.

https://www.npmjs.com/package/archiver

Cheers, Tim.

I create a project on github with a Hello World. When I run the command grunt lambda_package I have the same problem.

I will try to use the archiver package alone

I also tried to clone your project and run the tests. I have this error:

Hi, same problem, empty deploy package...

[Tim]

Hi @teu would it be possible to try a hello world example using the archiver package? https://www.npmjs.com/package/archiver

That will help narrow down if the issue is with the library which generates the zip or how it's been implemented here.

[Piotr Jasiulewicz]

Hi,

had same problem with local file and buffer on ubuntu (also on AWS Lambda) so switched to another library. time permitting will try to submit something.

I bumped the adm-zip version to the latest one which I hope will resolve this issue. I also tested it in a Windows 7 VM and it all worked fine.

I've just released a new version including the pull request from @qen so hopefully this will be fixed. Let me know how you go.
