Failed to create a campaign in MailerLite: Cannot read properties of undefined (reading 'length')

Trying to create a zap that goes as follows: when someone checks out through a Stripe payment link, they receive an e-mail through Mailerlite. However, I can’t send the e-mail through Mailerlite because the following message appears:

Cannot read properties of undefined (reading 'length')
