我想更改计费计划的金额，但在尝试更改时出现错误。如果计划已经有与之相关的协议，是否可以更改计划的条款 (payment_definitions)？

要求：

curl -v -k -X PATCH 'https://api.sandbox.paypal.com/v1/payments/billing-plans/[plan id]' \
-H "Content-Type: application/json" \
-H "Authorization: Bearer <Access-Token>" \
-d '[
    {
        "path": "/payment_definitions/[payment_definitions_id]/amount",
        "value": {
            "currency": "EUR",
            "value" : "10"
        },
        "op": "replace"
    }
]'
