为什么我的更新语句需要模式

Why does my update statement want a schema

我有一个 DataWeave 脚本可以从 phone 数字字段中删除所有非数字字符。该代码在 DataWeave Playground 中运行正常,但在 Anypoint Studio 中抛出错误。有效载荷是

{
  "Recipient": {
    "Name": "Bob Newhart",
    "MailingAddress": {
      "Line1": "123 Main Street",
      "Line2": "Apt 5",
      "City": "Cumming",
      "State": "GA",
      "ZipCode": "30009",
      "ZipCodePlus4": "3382"
    },
    "PhoneNumber": "(999) 555-1234",
    "Company": "Disney"
  }
}

脚本是

%dw 2.0
output application/json
---
(
  payload: payload update {case .Recipient.PhoneNumber -> replace (payload.Recipient.PhoneNumber, /\D/) with ""}
).payload

我是运行这个版本的Anypoint Studio

Version: 7.4.2
Build Id: 202001311805

Anypoint Studio返回的错误信息是: 无效输入“更新 {case”、预期架构或 &(第 6 行,第 20 列):

update operator was added in Mule 4.3.0。如果您使用的是较旧的 Mule 版本,它将不可用。估计Studio 7.4.2也不知道。
