eslint error - Missing semicolon - semi config is ignored

[milahu]

i removed .eslintrc in favor of .eslintrc.js
but eslint ignores my relaxed semicolon config

the config propagates to node_modules/eslint/lib/rules/semi.js
where options.omitLastInOneLineBlock is true
but still, it has no effect,
or there is a second pass of eslint that ignores my config

im stuck, please help : /

// .eslintrc.js

// debug
console.log('hello from .eslintrc.js');

module.exports = {
  rules: {
    // relaxed semicolon config
    semi: ["error", "always", { omitLastInOneLineBlock: true }],
  }
}

this .eslintrc is also ignored:

{
  "rules": {
    "semi": ["error", "always", { "omitLastInOneLineBlock": true }]
  }
}

// src/scripts/index.js

console.log('hello')
//                  ^ eslint error
console.log('world')
//                  ^ eslint error
