Error generating `parserServices` for eslint plugin `@typescript-eslint`

Versions:

prettier-eslint version: 8.8.2
node version: 11.9.0
yarn version: 1.13.0

Have you followed the debugging tips?

Yes

Relevant code or config

.eslintrc.js

parser: `@typescript-eslint/parser`,
parserOptions: {
  project: `./tsconfig.json`
},
rules: {
  '@typescript-eslint/no-unnecessary-type-assertion': 2
}

What I did: Run prettier (via VSCode`s FormatOnSave hook).

What happened:

Error while loading rule '@typescript-eslint/no-unnecessary-type-assertion'/home/oskar/dev/hyperapp/hyper-parcel/src/bootstrap.ts:: 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.

Problem description:

Running prettier-eslint I get the error above. Running eslint directly gives no errors and works as expected. I have also tried it with an absolute path to my tsconfig.json, but the error is the same.

@ricardolpd I was able to fix this by adding "project": ["tsconfig.json"],:

"parserOptions": {
  "ecmaVersion": 2020,
  "project": ["tsconfig.json"] ,
  "sourceType": "module"
},

could anyone provide an example of a config that provides a work around for this? We are facing this issue with '@typescript-eslint/require-await' in our mono repo.
