Repro

To the root of a project that is using EXPERIMENTAL_useProjectService: true recently I added rollup.config.js. That file was not added to tsconfig's include list. ESLint throws:

Error while loading rule '@typescript-eslint/consistent-type-exports': You have used a rule which requires parserServices to be generated. You must therefore provide a value for the "parserOptions.project" property for @typescript-eslint/parser.

By the way, it was so exciting to see the EXPERIMENTAL_useProjectService option added. The project I talk about is rather experimental so it was perfect playground to tryout the ProjectService.

ESLint Config

module.exports = {
  parser: "@typescript-eslint/parser",
  parserOptions: {
    "EXPERIMENTAL_useProjectService": true
  }
};

tsconfig

{
  "include": ["./src"]
}

Expected Result

Perhaps the error could be more useful. If this should be an error at all. Not sure what is going on.

Actual Result

Looking at the error, I thought that maybe the option was removed or stoped working.
