Anypoint CloudHub 中的转换连接器失败

Question

我有一个转换动作，其逻辑如下

%dw 2.0
import * from dw::util::Coercions
output application/json
---
{
   "quoteId" : vars.setQuoteOppRecIds.Id,
   "productCode" : payload.ServiceTypeCode,
   "axSequenceNumber" : vars.counter as Number,
   "phaseLevel" : payload.PhaseLevel as Number,
   "phaseLevelDescription": payload.PhaseLevelDescription,
   "projectWeekStart" : payload.PhaseLevelProjectWeekStart as Number,
   "projectWeekEnd" : payload.PhaseLevelProjectWeekEnd as Number,
   "quantity": payload.Quantity as Number,
   "invoicedSinceLast" : payload.InvoicedSinceLast as Number, 
   "unitPrice": (payload.UnitPrice replace "," with "") as Number {format: ".00"} as String {format: ".00"} as Number,
   "oppId" :  if (isEmpty(vars.inputPayload.Opportunity.OpportunityId)) (vars.oppID) else (vars.inputPayload.Opportunity.OpportunityId) 
}

在本地调试此转换时，它可以正常工作，但在部署到 CloudHub 后，它会抛出类似

的错误

Unable to resolve module with identifier dw::util::Coercions. at 2 : 2
    at org.mule.weave.v2.el.WeaveExpressionLanguage.compile(WeaveExpressionLanguage.scala:68)

我是 mulesoft 的新手我在本地调试时没有捕获到这个错误，但是为什么当运行 CloudHubAPI 中的

时它会抛出

Answer 1

脚本中使用的 DataWeave 包 dw::util::Coercions was added to Mule since Mule 4.4.0. 您可能在 CloudHub 中部署到不支持它的早期版本的 Mule。将应用程序重新部署到 Mule 4.4.0，它应该可以工作。

或者，由于您的脚本不使用该包提供的任何功能，您可以删除导入行。
