TypeScript error TS5023: unknown compiler option 'strict'

Question

When using the strict option in a file, tsconfig.jsonI get an error message:

error TS5023: Unknown compiler option 'strict'

But this compiler option is explicitly allowed in the official documentation:

Link: https://www.typescriptlang.org/docs/handbook/compiler-options.html

As well as my Visual Studio Code Editor.

Does anyone know what I did wrong? Here is my tsconfig.json file:

{
  "compilerOptions": {
    "strict": true,
    "sourceMap":  true
  }
}
