## Common causes

- You're trying to update a subscription that has a scheduled change using a `proration_billing_mode` that bills on the next billing period, which isn't allowed.

## Common solutions

- Use `do_not_bill`, `full_immediately`, or `prorated_immediately` for the `proration_billing_mode`.
- Remove the scheduled change to use any `proration_billing_mode`.
