Getting FileError

[sanledi-buli]

Hi, I'm sorry for this dummy question. I tried this on my ionic application with function:

var fs = new CordovaPromiseFS({
        Promise: $q
      });
      // Initialize a CordovaAppLoader
      var loader = new CordovaAppLoader({
        fs: fs,
        serverRoot: 'http://localhost:3000/',
        localRoot: 'app',
        cacheBuster: true, // make sure we're not downloading cached files.
        checkTimeout: 10000 // timeout for the "check" function - when you loose internet connection
      });
      loader.check().then(function (updateAvailable) {
        console.log(updateAvailable);
        if (updateAvailable)
        {
          loader.download(onprogress)
            .then(
              function (manifest)
              {
                console.log(manifest);
                loader.update();
              },
              function (failedDownloadUrlArray)
              {
                console.log(failedDownloadUrlArray);
              }
            )
        }
      });

But I got error ->
FileError {code: 10, name: "QuotaExceededError", message: "The operation failed because it would cause the application to exceed its storage quota."}

Thank You.
