Providing more than one argument for custom integrated terminal profile fails on osx

[alexg9010]

Type: Bug

I have a custom terminal created for running tmux defined in my user settings:

{
  "terminal.integrated.profiles.osx": {
        "tmux": {
            "path": "bash",
            "args": [
                "-c", 
                "tmux new -ADs vscode-${PWD##*/}"
        ],
            "icon": "terminal-tmux",
        },
    },  
    "terminal.integrated.profiles.linux": {
        "tmux": {
            "path": "bash",
            "args": [
                "-c",
                "tmux new -ADs vscode-${PWD##*/}"
            ],
            "icon": "terminal-tmux",
        },
    },
    "terminal.integrated.defaultProfile.osx": "tmux",
    "terminal.integrated.defaultProfile.linux": "tmux"
}

This works on a remote machine with Linux and used to work on macOS.

The process fails with error code 127, but when expecting the generated command I noticed that there is an additional , between the arguments passed to bash, which is not occurring on the remote machine.

error message on local macOS:
