Error message

Subscription update results in a transaction that has more than the maximum number of line items.

Common causes

• You're trying to add more than 100 recurring items to a subscription.
• You're billing changes on the next billing period, but line items for earlier changes or one-time charges are already scheduled for renewal, pushing the next transaction over 100 line items.
• You're replacing too many recurring items at once, pushing the next transaction over 100 line items.

Troubleshooting

• Reduce the number of recurring items on the subscription to 100 or fewer.
• Get a subscription with next_transaction to preview the line items scheduled for the next transaction.
• Use prorated_immediately or full_immediately as the proration_billing_mode to bill changes immediately rather than adding them to the renewal transaction.
