Repro Code

constparserServices=getParserServices(context,true);

ESLint Config

{"parser":"@babel/eslint-parser","parserOptions": {"ecmaVersion":"latest","requireConfigFile":false,"babelOptions": {"babelrc":false,"configFile":false    }  }}

tsconfig

{"compilerOptions": {"lib": ["ESNext"],"module":"commonjs","moduleResolution":"node","skipLibCheck":true,"target":"ESNext"  },"files": ["file.ts"]}

Expected Result

typeofparserServices should beParserServicesWithoutTypeInformation

Actual Result

An error is thrown:

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.

Additional Info

This check is testing fornull orundefined but mycontext.parserServices is an empty object and thus the error is thrown.

https://github.com/typescript-eslint/typescript-eslint/blob/v6/packages/utils/src/eslint-utils/getParserServices.ts#L35-L39

Edit: Looks likeparserServices isn't actually set directly on thecontext object but is instead being inherited through its prototype chain.
