Fatal error: handle is not a Buffer while doing scp

[shabfactor]

my gruntfile.js is below

  secret: grunt.file.readJSON('environment.json'),
  scp: {
       test:{
         options: {
           host: '<%= secret.server1.host %>',
           username: '<%= secret.server1.username %>',
           privateKey: '<%= grunt.file.read(secret.server1.privateKey) %>',
           showProgress: true
          // tryKeyboard: true
         }, 
         files: [{
             cwd: './dist',
             src: '**/*',
             filter: 'isFile',
             dest: '/path/to/folder/project.test'
         }]  
       },
       prod: {
         options: {
           host: '<%= secret.server2.host %>',
           username: '<%= secret.server2.username %>',
           privateKey: '<%= grunt.file.read(secret.server2.privateKey) %>',
           tryKeyboard:true
         },
         files: [{
             cwd: './dist',
             src:'**/*',
             dest:'/srv/www/vhosts/project'
         }]
       } 
   } `

what i figure out is when it does scp it does not set proper rights on the folder which should be 775 so please tell me a way to set rights while doing scp in grunt.

In the files configurations you must add 'filter': 'isFile'.

The plugin manage all entries as files and fails when any entry is a folder.

This issue is always caused by File perms - the above method may not fix your problem

1. Check the path on the target - that the user your 'scp' ing to has perms to read, write and traverse that directory
2. Check existing files in the directory have the same permissions for that user -

use grunt -v scp:your_target and review the error - if it shows a path similar to
path/directory/newfile.ext/newfile.ext it means it cannot overwrite the existing file.

You can use file access lists if required to set the perms correctly.
