My leads keep getting stuck on this email in my journey, the leads enter into the journey fine and there is no personalisation in the email but they will not go past this stage.
There is an error when you go into journey history:
Failed - A subscriber error occured invoking triggered send. StatusMessage: Unable to queue Triggered Send request. There are no valid subscribers.ErrorCode: 180008 SubscriberFailureDescription: Error Code: 10 - The subscriber is missing required attribute value for Full Address.
But "Full address" isn't required.
Can anyone help please?
