@YoussefACHCHIRAJ added support for newsletter mails, I think you should downgrade back to pre-last release until the CLI developer fix this, thank you!

[elnasnato]

@elnasnato The issue comes from the PHP version you’re running. I updated the syntax so it works on older versions as well.
Thanks for bringing this to our attention!
