Hi VS Code dev here 👋 Please stop using the `enableBreakpointsFor` field in your `package.json`. It is deprecated and we will stop supporting it in our next stable release (in a month). Here's where you use it https://github.com/felixfbecker/vscode-php-debug/blob/master/package.json#L119 Here's an alternative how you should use it https://github.com/microsoft/vscode-mock-debug/blob/master/package.json#L112 So the `breakpoints` attribute is no longer under `debuggers` that is the difference. Here's how react native tackled this deprecation https://github.com/microsoft/vscode-react-native/issues/1450 All the best isidor
