"Reload the scp config from project" on Save

[mishaonmac]

The extension shows "Reload the scp cofng from project" message in the bottom right corner of VS Code window after each attempt to save current file. Nevertheless, corresponding file on the remote device is updated.
I am running VS Code 1.75 on Ubuntu 20.04 LTS. The remote device runs embedded linux (PetaLinux 2021.2). The ssh certificate (empty password) is installed on the device for the user.
scp.json:
{ "host": "192.168.0.192", "port": 22, "user": "peta", "ignore": [".git",".vscode", "__pycache__"], "remotePath": "/home/peta/project", "identity_file": "~/.ssh/id_rsa", "uploadOnSave": true }
