Using ESLint through "ng lint" CLI command returns error "All files matching the following patterns are ignored: - '/src/**/*.ts' - '/src/**/*.html'

Question

I'm trying to run ESLint through the ng lint CLI command, but it fails, returning the following error:

Error when running ESLint: All files matching the following patterns are ignored:
- '/src/\*\*/\*.ts'
- '/src/\*\*/\*.html'

Please check your '.eslintignore' file.

I do not have a .eslintignore file. I tried creating one, but it didn't change the outcome.

I tried adding --no-ignore (as per Google AI suggestion) but it is not accepted.

angular.json config related to linting

...
        "lint": {
          "builder": "@angular-eslint/builder:lint",
          "options": {
            "lintFilePatterns": [
              "/src/**/*.ts",
              "/src/**/*.html"
            ]
          }
        }
...

I tried not giving lintFilePatterns, but then I get following error:

Error: Schema validation failed with the following errors:
  Data path "" must have required property 'lintFilePatterns'.

eslint.config.mjs:

import typescriptEslint from 'typescript-eslint';

export default typescriptEslint.config(
  { ignores: [ '.angular/**', 'dist/**', 'node_modules/**' ] },
  {
    name: 'Basic JS/TS PIT ESLint config',
    files: [ '**/*.js', '**/*.cjs', '**/*.mjs', '**/*.ts' ],

    },
  }
);

Finally found what is wrong:

 ...
        "lint": {
          "builder": "@angular-eslint/builder:lint",
          "options": {
            "lintFilePatterns": [
              "src/**/*.ts",
              "src/**/*.html"
            ]
          }
        }
...

Notice the absence of forward slashes before the 2 paths in the "lintFilePatterns" section.
