resend confirmation email never finds email

Other emails are working (events updates, change password, account creation...), but when we click on "resend confirmation email", Mobilizon does not find the user. The JS console says this:

GraphQL error: Aucun·e utilisateur·ice à valider avec cet email n'a été trouvé·e

nothing appears in the email logs on the server.

can be seen here: https://mobilizon.chapril.org/resend-instructions and here https://events.chapril.org/resend-instructions
