Problem with drush and site alias (Drupal 8.8.6 / Drush 10.3.1) I've installed two drupal sites on a share hosting (OVH), in two folders :

dev.www
www

I've installed drush 10.3.1 and create two alias, but when I try use alias (drush @dev status), I have the follow error :
[warning] Drush command terminated abnormally.

I don't know if my drush configuration or aliases are good or bad. Here is my configuration in .drush/sites/the-choices.site.yml:
'@the-choice.dev':
  remote-host: ...
  user: ...
  root: /home/thechoc/dev.www
  uri: 'http://dev.the-choice.org'
  ssh:
    options: '-o PasswordAuthentication=no -i /home/thechoc/dev.www/insecure_private_key'
'@the-choice.prod':
  host: ...
  user: ...
  root: /home/thechoc/www
  uri: 'https://the-choice.org'
  ssh:
    options: '-o PasswordAuthentication=no -i /home/thechoc/www/insecure_private_key'

If someone can help me. Thank in advance.
There is no need for the leading @name and try adding the full path to drush for all remote environments:
dev:
  ...
  paths:
    drush-script: /example/path/www/vendor/drush/drush/drush
prod:
  ...
  paths:
    drush-script: /foo/bar/www/vendor/drush/drush/drush
