Steps to reproduce the problem

{
  "name": "ts-node",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "tsconfig": "ts-node --showConfig",
    "serve": "ts-node ./src/index.ts"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "@tsconfig/node16": "^1.0.2",
    "ts-node": "^10.7.0",
    "typescript": "^4.6.4"
  }
}

.vscode

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "Launch Program",
      "runtimeArgs": ["-r", "ts-node/register"],
      "args": ["${workspaceFolder}/src/index.ts"],
      "env": {
        "TS_NODE_PROJECT": ".vscode/tsconfig.json"
      }
    }
  ]
}

vscode debug will regenerated new transpiled file

it should be source file is fine.

Minimal reproduction

Specifications

• ts-node version: "^10.7.0",
• node version:v17.6.0
• TypeScript version:"^4.6.4"
• tsconfig.json, if you're using one:

{
  "extends": "@tsconfig/node16/tsconfig.json",
  "ts-node": {
    // It is faster to skip typechecking.
    // Remove if you want ts-node to do typechecking.
    "transpileOnly": true,
    "files": true,
    "compilerOptions": {
      // compilerOptions specified here will override those declared below,
      // but *only* in ts-node.  Useful if you want ts-node and tsc to use
      // different options with a single tsconfig.json.
      "outDir": "./dist",
      "sourceMap": true
    }
  },
  "compilerOptions": {
    // typescript options here
    // "jsx": "react-jsx"
    "sourceMap": true
  }
}

• Operating system and version:
• If Windows, are you using WSL or WSL2?:

What operating system and version? Can we get a copy of that error as text instead of screenshot?

Can we also get a copy-paste of the emitted index.ts shown in your editor, including the complete sourceMappingURL comment? I want to ensure it is all valid, to rule out VSCode bugs. Because based on that screenshot, it looks like VSCode is incorrectly parsing the sourcemap comment; it's off by 6 characters. (specifically, data:a)

[tianyingchun]

you are right, i changed vscode to another version issue is gone.

[cspotcode]

Which version were you using before, and which did you switch to? If someone else has the same problem, they will probably find this issue and want to know the answer. It would be nice for us to help them.

[tianyingchun]
