## Details

| Attribute | Value |

## Common causes

- The request adds `allowances` to a price that has a `trial_period`.
- The request includes both `allowances` and `trial_period` when creating a price.
- The request adds a `trial_period` to a price that has `allowances`.

## Common solutions

- To include allowances, remove the trial period. Omit `trial_period` when creating the price, or set it to `null` when updating it.
- To keep the trial period, remove the allowances. Omit `allowances` when creating the price, or set it to an empty array (`[]`) when updating it.
