Manual SCP works, sync download works, sync upload permission denied

[ahtarr]

I can manually move files to my remote system using (details changed obviously):

scp ./directory/index.js [email protected]:/path/to/directory/index.js

I am prompted for my password, I enter it, and the transfer proceeds.

My .remote-sync.json looks like this:

{
"logger": {
"title": "Remote Sync"
},
"transport": "scp",
"hostname": "10.20.30.40",
"username": "myname",
"password": "*****!",
"target": "/path/to/directory",
"ignore": [
".remote-sync.json"
],
"uploadOnSave": false,
"useAtomicWrites": false,
"deleteLocal": false,
"watch": [],
"port": "22"
}

Downloading succeeds. Uploading fails with the message "Error: Permission denied".

Any suggestions?

Thanks.
