MBE-535 mirrord + vscode + templating seems to get ide to hang

after trying out a few different launch configs, i think the issue may be down to the env field - out of the two following launch configs, the first works with and without mirrord enabled, but the second only works without mirrord (and hangs when mirrord is on):

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Next.js: Working",
            "type": "node",
            "request": "launch",
            "skipFiles": [
                "<node_internals>/**"
            ],
            "runtimeExecutable": "npx",
            "runtimeArgs": [
                "next",
                "dev"
            ],
        },
        {
            "name": "Next.js: Non-working",
            "type": "node",
            "request": "launch",
            "skipFiles": [
                "<node_internals>/**"
            ],
            "runtimeExecutable": "npx",
            "runtimeArgs": [
                "next",
                "dev"
            ],
            "env": {
                "NODE_OPTIONS": "--inspect"
            },
        }
    ]
}

now, we just need to find out what the problem is with using env

for now, i think the following configuration should work and do the same thing :) the --inspect flag can only be set in NODE_OPTIONS, and there looks to be interference with mirrord concerning the port that the process listens to - to prevent the hanging until this is fixed, remove --inspect altogether

 { "version": "0.2.0",
  "configurations": [ {
      "name": "NEW",
      "request": "launch",
      "runtimeArgs": [
        "next",
        "dev"
      ],
      "runtimeExecutable": "npx",
      "skipFiles": [
        "/**"
      ],
      "type": "node",
      "outFiles": [
        "${workspaceFolder}/x/**/*.(m|c|)js",
        "!**/node_modules/**"
      ],
      "cwd": "${workspaceFolder}/apps/x",
    }
  ]
}

mirrord is being loaded into vscode's watchdog extension (which looks to be an activity monitor or some sort) and then trying to render the config with Tera - the call to get_env() is then hanging. This can be worked around by adding a default value, for example "header_filter": "x-intercept: {{ get_env(name="USER",default="default") }}" but should be fixed long-term by stopping mirrord from loading into this process altogether
