I am trying Node.js to upload multiple files from my Google Compute Engine VM local directory to a GCS bucket that I have already created. I am getting the following error each time I am running the script.

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type function

The script:

 `// Imports the Google Cloud client library

const {Storage} = require('@google-cloud/storage');

const fs = require ('fs');

const glob = require('glob');



// The name of the bucket to access, e.g. "my-bucket"

   const bucketName = "myBucket";





// Instantiates a client

const storage = new Storage({

  projectId: 'myprojectID', 

  keyFilename: 'my GCS service key'

});



//get files in the local directory of VM 



var allfiles = glob('folder/*.js', function (err, files) { 

    if (err) { 

        console.log(err); 

    }  

});





// Uploads VM local dir files  to the bucket

storage

  .bucket(bucketName)

  .upload(allfiles)

  .then(() => {

    console.log(`${allfiles} uploaded to ${bucketName}.`);

  })

  .catch(err => {

    console.error('ERROR:', err);

  });'

Apparently the 'Upload' process needs the file pathnames as string. But that's what the Glob function is supposed to do. Still why is the error?

Any help will be seriously appreciated!

Your mistake is that you use allfiles as the return value for glob. This is not correct, the file names are available in the callback (since glob is async), not in the return value.

glob('folder/*.js', function (err, files) { 

    if (err) { 

        console.log(err); 

    }



    var allfiles = files;



    // Uploads VM local dir files  to the bucket

   storage

  .bucket(bucketName)

  .upload(allfiles)

  .then(() => {

    console.log(`${allfiles} uploaded to ${bucketName}.`);

  })

  .catch(err => {

    console.error('ERROR:', err);

  });'  

});
