Sync not working with Tasks: Run Task

[Dylan190774]

I created a task in VSCode to run the sync command, but it's not working. Here's my tasks.json:

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "SFTP Sync Local -> Remote",
            "command": "${command:sftp.sync.localToRemote}",
            "type": "process",
            "problemMatcher": [],

        }
    ]
   }

When I run the task via the command pallette 'Tasks: Run Task' I get the following error:

 *  Executing task: <...my local path...>\sftp.sync.localToRemote  
 *  The terminal process failed to launch: Path to shell executable '_<...my local path...>_\sftp.sync.localToRemote" does not exist. 

And when I try to run the task with an extension called Task Explorer I get: [error] Error: Config Not Found. (file:///${command:sftp.sync.localToRemote})

The sync command however does work when I use a keybinding. It then asks 'Select a folder' after which it runs fine.

Any ideas?
