Configuration file .remote-sync.json not ignored when uploading folder

[mengqigu]

I'm uploading my local project directory to a server using SCP with private keys. Here is what the configuration file looks like:

{
"uploadOnSave": false,
"useAtomicWrites": false,
"deleteLocal": false,
"hostname": "my.website.com",
"port": "22",
"target": "/home/target",
"ignore": [
".remote-sync.json",
"123.txt"
],
"username": "myName",
"keyfile": "/path/to/key",
"passphrase": "myPassPhrase",
"watch": [],
"transport": "scp"
}

After I selected "Upload Folder", file .remote-sync.json was still uploaded to the server, while file 123.txt was not.
