Error message

This transaction is manually-collected and has items where some items require a payment method in trial, which isn't allowed.

Common causes

• You're trying to create a transaction where collection_mode is manual, with items where trial_period.requires_payment_method is false.

Troubleshooting

• Modify the items on your transaction so that it doesn't contain any prices where trial_period.requires_payment_method is true.
• Update prices on the transaction so that trial_period.requires_payment_method is false, then try your request again.
• Consider changing transaction collection_mode to automatic to bill using a checkout and automatically renew using a saved payment method.
