User input variables in launch config are broken

[roblourens]

• Add one of the special input to some launch config, like

"cwd": "${input:cwd}"

• Start the launch config
• Get "Cannot read property 'filter' of undefined"

From

vscode/src/vs/workbench/services/configurationResolver/browser/configurationResolverService.ts

Line 231 in 6a7d02f

const info = inputInfos.filter(item => item.id === variable).pop();

I cannot reproduce.

Please note that "input" variables require a proper "input" section in the launch.json, e.g. this:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Hello World",
            "cwd": "${input:cwd}",
            "runtimeExecutable": "foo"
        }
    ],
    "inputs": [
        {
            "id": "cwd",
            "type": "promptString",
            "description": "Please enter a cwd value",
            "default": "default_cwd"
        }
    ]
}

This works fine.

But even if the "input" section is missing like here:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Hello World",
            "cwd": "${input:cwd}",
            "runtimeExecutable": "foo"
        }
    ]
}

I get a proper error message:

@roblourens in which version of VS Code are you seeing this?
How does your "input" section looks like?

@roblourens ping?

Oh I forgot about the inputs section. But when that is missing, that's when the unhelpful error message shows up.
