Debug adapter process has terminated unexpectedly

[tekord]

Hi! Thanks for nice extension. But I have some issues with it. The most important for me now is not working debugger. It worked earlier, but I edited launch configuration and VS showed me the error: "Debug adapter process has terminated unexpectedly". I returned my launch configuration back, but it didn't help. My current launch configuration is:

        {
            "name": "ANTLR",
            "type": "antlr-debug",
            "request": "launch",
            //"input": "${workspaceFolder}/${command:AskForTestInput}",
            "input": "tests/input.qs",
            "grammar": "QaterParser.g4",
            "startRule": "program",
            "printParseTree": true, // I removed this line when I got the error in first time
            "visualParseTree": true
        },

My workspace config is the following:

    "antlr4.generation": {
        "mode": "internal",
        "outputDir": "generated",
        "language": "Cpp", // I know this is not used when mode is 'internal'
        "listeners": false,
        "visitors": true
    },

Oh, i disabled all C++ and C# extensions, restarted VS and the error is gone.

Hmm, so it seems some other extension has side effects? You could try to enable them back, one by one, to find out what the real culprit is. In any case I guess we can close this issue, right?

Has this issue been resolved?

Same on me, my launch.json:

{
  "version": "2.0.0",
  "configurations": [
    {
      "name": "antlr4-tokenRegexIt",
      "type": "antlr-debug",
      "request": "launch",
      "input": "examples/literal.txt",
      "grammar": "TokenRegexIt.g4",
      "startRule": "query",
      "printParseTree": true,
      "visualParseTree": true
    }
  ]
}

setting.json

{
  "antlr4.generation": {
    "mode": "external",
    "language": "JavaScript",
    "outputDir": "./src/antlrGeneratedParser",
    "listeners": true,
    "visitors": true
  },
  "antlr4.referencesCodeLens.enabled": true
}

Should I change something on "antlr4.debug": {},?

Solved, my fault, I didn't notice that "startRule" means the rule in .g4 file. I thought It was a vscode task setting.
