Property 'entries' does not exist on type 'ObjectConstructor' with lib and target set

I'm trying to use a Map using JSON parse this way:

Object.entries((JSON.parse(variables)))

and the compiler throws the error

Property 'entries' does not exist on type 'ObjectConstructor'

But the method works and I'm able to retrieve my map. I've looked for other questions and changed target and lib inside tsconfig files. Inside tsconfig.app.json I have:

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "module": "es2017",
    "target": "ESNext",
    "baseUrl": "",
    "types": [
      "node"
    ],
    "lib": [
      "es2018",
      "dom"
  ]
  },
  "exclude": [
    "test.ts",
    "**/*.spec.ts"
  ]
}

and in tsconfig.spec.json:

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/spec",
    "module": "commonjs",
    "target": "ESNext",
    "baseUrl": "",
    "types": [
      "jasmine",
      "node"
    ],
    "lib": [
      "es2018",
      "dom"
  ]
  },
  "files": [
    "test.ts",
    "polyfills.ts"
  ],
  "include": [
    "**/*.spec.ts",
    "**/*.d.ts"
  ]
}

I thought it was enough to set target and lib but it keeps not working. What else is it to change to remove compiler error?

Have you restarted ng serve? – MauriceNino May 13 '19 at 12:18
@MauriceNino the error is at build, not during dev. He specified that already. – May 13 '19 at 12:21
@trichetriche where does he specify this? Am I blind? – MauriceNino May 13 '19 at 12:23
@MauriceNino I've restarted it but it gives this error after compiling: `ctorParameters.map is not a function` – Usr May 13 '19 at 12:24
And what is `ctorParameters`? – MauriceNino May 13 '19 at 12:26
@MauriceNino `I'm trying to use a Map using JSON parse this way (...) and the compiler throws the error (...) But the method works and I'm able to retrieve my map` – May 13 '19 at 12:26
@MauriceNino I don't know, it's not in my code. – Usr May 13 '19 at 12:27
@trichetriche and? that does not state that it happens at build. Compiletime is also on every save with `ng serve` – MauriceNino May 13 '19 at 12:28
@Dseaster Maybe [this](https://stackoverflow.com/questions/41285889/ctorparameters-map-is-not-a-function-in-angular2-mdl)? – MauriceNino May 13 '19 at 12:29
@MauriceNino you're right, I assumed. Should've known by now not to assume on SOF ... My bad ! – May 13 '19 at 12:29
