I'm trying to transpile my code typescript using grunt-ts with tsconfig.file. When I run the command npm run grunt the follow error was shown:

➜  backend git:(master) ✗ npm run grunt

In tsconfig.json already has the option resolveJsonModule, but was ignored.

{
    "compilerOptions": {
        "module": "commonjs",
        "resolveJsonModule": true,
        "esModuleInterop": true,
        "target": "ES5",
        "allowJs": true,
        "moduleResolution": "node",
        "sourceMap": true,
        "outDir": "dist",
        "rootDir": "src",
        "strict": true
    },
    "include": [
        "src/**/*",
        "src/**/*.json"
    ],
    "exclude": [
        "node_modules",
        "**/*.test.ts",
        "jest.config.js"
    ]
}

This is the gruntfile.js:

module.exports = (grunt) => {
  grunt.initConfig({
    ts: {
      default: {
        tsconfig: './tsconfig.json',
      },
    },
  });
  grunt.loadNpmTasks('grunt-ts');
  grunt.registerTask('default', ['ts']);
};

If I run only tsc, the process runs successfully

in the readme there is a way to pass tsconfig as an object. What you want to do is pass it that way in your Gruntfile and use passthrough true. The docs have the exact syntax
