If you want to make sure that the value inside en is not empty, you can use the following:

const {check, validationResult} = require('express-validator');

app.post(
    '/addresses',
    check('text_settings_descriptions.en.value').notEmpty(),
    (req, res) => {
        const errors = validationResult(req);
        console.log(errors);
        // ... handle errors and request
    },
);

With above code if the value was an empty value, the follwoing will be logged to the console:

 {
  formatter: [Function: formatter],
  errors: [
    {
      value: '',
      msg: 'Invalid value',
      param: 'text_settings_descriptions.en.value',
      location: 'body'
    }
  ]
}
