SSH Tunnel Identity File not working

[appfeel]

Bug Report

Current Behavior

When trying to create a SSH tunnel with identity file it does not load the key file:

1. Create connection with connectionString
2. Select Proxy/SSH
3. Select SSH with Identity File
4. Fill the form (also note that labels are not visible by theme colors)
5. File does not seem to be selected (tried with different keys: rsa, ed25519)
6. Save & connect
7. ERROR: When connecting via SSH tunnel either password or identity file is required.

Code/Gist

Also tried to configure the connection via workspace but it does not work:

        "mdb.presetConnections": [
            {
                "name": "db-prod",
                "connectionString": "mongodb://user:pw@localhost:27017/db-prod?authSource=db-prod",
                "sshTunnel": "IDENTITY_FILE",
                "sshTunnelUsername": "user",
                "sshTunnelHostname": "server.com",
                "sshTunnelPort": 22,
                "sshTunnelIdentityFile": ["/Users/user/.ssh/id_ed25519"],
            }
        ]

@appfeel thanks for opening the issue. The labels not showing up is definitely a new bug, I created VSCODE-810 to track a fix for that.

It does look like there's a bug with selecting files in the connection form as well 😞 . Created VSCODE-811 to track a fix there.

Unfortunately we only allow connection strings with presetConnections at the moment, SSH tunnel options aren't something that we support there at the moment.

Thanks again for letting us know, hopefully we can get a fix out soon.
