无法从文本单元格Mule Dataweave获取数值

我正在使用File connector读取数据，并使用data weave将数据转换为application/java。如果excel中有任何单元格的类型为Accounting，则会出现此异常：

消息：无法从文本单元格获取数值（java.lang.IllegalStateException）。 有效载荷：com.mulesoft.weave.reader。DefaultSeekableStream@6fe3727f

---

如果单元格格式更改为“常规”，则异常消失。我如何才能在excel中使用记帐类型的单元格？

我在本地anypoint studio中创建了相同的场景，最初使用studio版本6.2.3，Mule runtime 3.8.1 EE遇到了几个问题。我将运行时更新为3.8.3ee，所有问题都解决了&一切似乎都很正常。验证是否存在任何版本问题，excel支持最近添加到dataweave中，并且仍处于测试阶段

这是对我有用的流程

请提供导致异常%dw 1.0%output application/java---payload.“Sheet1”映射（（Sheet1，indexOfSheet1）->{id:Sheet1.id}）的excel文档和dataweave。您是否使用了我附加为输入源的excel？我使用的是3.8.3 EE运行时版本。我的流程可以成功读取excel文件，但无法读取我附加的文件。这是因为“金额”字段的数据类型。如果单击“格式单元格”，您将看到它是记帐。如果我把它改为“一般”，一切都很好。如果excel输入源中有任何会计格式的字段，我如何才能使其正常工作？我从google drive下载了您的文件，运行起来似乎很好，但它也会生成空白单元格。我将日志消息添加到我的答案中。当然，flow正在读取文件，并且在拾取后将其删除，因为我没有将autoDelete设置为false。文件名模式是可选的参数，在我添加到流之后仍然像往常一样运行。请告诉我任何问题。您没有看到前两个有效项“{id=1234，amount=500.5}，{id=456，amount=700.25}”。铰孔数据为空单元格，因为您的文件有问题。抱歉，我看不到前两项
