将Oracle SYSTEM.DATA.DATATABLE结果作为参数传递给另一个powershell脚本时出错

我正在编写一个脚本，该脚本将执行以下操作：

连接到Oracle DB并运行主查询以提取原始数据。-已经作为单元测试工作

将原始数据导入Microsoft access数据库模板（.mdb）-以单元测试方式工作，但与脚本1集成时遇到错误

连接到MS Access数据，运行筛选（子）查询，并将结果导出到单独的excel选项卡中。-已经作为单元测试工作

*无法直接在Oracle数据库上运行（子）查询，因为在Oracle数据库上执行的查询（原始数据）大约需要5个小时，因此原始数据将首先导入Microsoft access进行处理，然后运行（子）查询

我已经为每个项创建了Powershell脚本，并创建了一个主脚本，用于调用和提供每个项的参数。它们已经过单元测试

1-01.dbquery.ps1

[参数：无；返回：原始数据]

2-02.mdbimport.ps1

[参数：原始数据（来自1），MDB文件返回：无]

3-03.mdb export.ps1

[参数：EXCEL文件，mdb文件；返回：无]

master script.ps1

但是，在集成脚本1和脚本2时，我遇到了错误

System.Management.Automation.ParameterBindingException:找不到接受参数“System.Data.DataRow”的位置参数。

请注意，脚本1从Oracle DB上的查询结果返回System.Data.Datatable值，我试图找出脚本2似乎不接受此值的原因。我还尝试在参数声明中声明类型

System.data.datarow

，但仍然无效，因为我得到了错误

Cannot process argument transformation on parameter 'RawData'. Cannot convert the "System.Data.DataRow System.Data.DataRow System.Data.DataRow System.Data.DataRow System.Data.DataRow System.Data.DataRow" value of type "System.String" to type "System.Data.DataRow".

下面是每个脚本的代码片段
