What means 'Parsing error: "parserOptions.project" has been set for @typescript-eslint/parser.' error in IntelliJ IDEs family?

Question

When I open .vue file, below error appears in my IntelliJ IDEA:

Parsing error: "parserOptions.project" has been set for @typescript-eslint/parser.
The file does not match your project config: XX\XX\CurrentFile.vue.
The file must be included in at least one of the projects provided.

Of course I will be glad if you teach me the solution, but first what I know what it means and WHY it appears.

I suspect that it is a some kind of bug, or inaccurate error message. Experimentally known what:

1. Sometimes it appears, sometimes - no.
2. It always appears when update eslint.
3. If to run eslint from console for some .vue file, eslint will finish the execution correctly. So seems like it is no eslint bug.

My Eslint config (YAML):

parser: vue-eslint-parser
parserOptions:
  parser: "@typescript-eslint/parser"
  sourceType: module
  project: tsconfig.json
  tsconfigRootDir: ./
  extraFileExtensions: [ ".vue" ]

env:
  es6: true
  browser: true
  node: true

plugins:
  - "@typescript-eslint"
  - vue


rules:
  // ...

TypeScript settings:

{
  "compilerOptions": {

    "target": "ES2017",

    "module": "CommonJS",
    "moduleResolution": "node",
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,

    "sourceMap": true,

    "experimentalDecorators": true,
    "skipLibCheck": true,

    "strict": true,
    "noUnusedParameters": true,
    "noImplicitReturns": true,

    "importsNotUsedAsValues": "preserve", // Limitation of the transpileOnly mode from ts-loader for .vue files.

    "baseUrl": "./",
    "paths": {
      // ...
    }
  }
}

You need to add your files to the include array in your tsconfig:

"include": [
  "path/to/src/**/*"
]
