Could you please share your tsconfig file?

Needs to be under the first level of tsconfig instead of compilerOptions.

{
  "compileOnSave": false,
  "include": ["node_modules/angular-bootstrap-md/**/*.ts",  "src/**/*.ts"],
  "compilerOptions": {
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "typeRoots": [
      "node_modules/@types"
    ],
    "lib": [
      "es2017",
      "dom"
    ]
  }
}

Please add below properties into tsconfig.json: "compileOnSave": false, "include": ["src/*/.ts"], "files": [ "src/app/mocked_data.ts" ], "compilerOptions": {...

Make sure to add these "include" and "files" properties before "compilerOptions". The "files" property should contain the path of the ts file within the project (which is src/app/mocked_data.ts in my example).
