Yes the page cannot be found because the contact is not existing anymore. What do you think we should have as page ? 404 ? Or a message like "your profile has been deleted before your request" ?

Hi!
Thank you for the quick answer.
Maybe something like Record not found will be much better than internal server error
Mautic already has this message, why not to use that?
But if this is the expected situation I will try to find my own workaround.
