Vscode-react-native: Add configuration not working - react native tools

[springcoil]

Issue Type: Bug

Hi, I wanted to use React-native debugger like this tutorial - https://github.com/Microsoft/vscode-react-native/blob/master/README.md#debugging-react-native-applications. However I'm running into problems getting it to work. I click on 'Add Configuration' in launch.json and nothing happens. I see no change. I expected that this would offer me some options. https://github.com/Microsoft/vscode/issues/63242 is a related issue I believe.

Extension version: 0.9.2

Hi @springcoil and thanks for reaching us. Is Add configurations button grayed out in your case?

[springcoil]

Hi @ruslan-bikkinin no it's not greyed out. I've got a screenshot.

Usually it should be gray when launch.json is malformed. In your case just add these lines to launch.json to make it work again:

{
    "version": "0.2.0",
    "configurations": [
    ]
}

[springcoil]

Thanks so much. I'm happy with that resolution. Can I open a PR to just add this to the FAQs?

@springcoil I believe this is a regression in VS Code issue because Add configuration button supposed to be disabled in the past in cases like yours. I'd suggest you to let VS Code team know about it, as well, unless there is similar issue opened already.
