When pasting this YAML file into an online yaml parser, I got an expected block end error:
ADDATTEMPTING: \'Tentative d ajout \' ATTEMPTINGTOGIVE: \'Tenter de do
The line starting ALREADYEXISTS uses ’ as the closing quote, it should be using '. The open quote on the next line (where the error is reported) is seen as the closing quote, and this mix up is causing the error.
ALREADYEXISTS
