我正在尝试使用PDI生成pdf文件，方法是使用pentaho报告输出组件将参数传递给prpt。
但是，当我尝试运行转换时，它会产生如下错误。 请帮我解决这个问题。

我尝试使用PDI V8.0和PR V8.0。如果我需要添加任何插件或任何修改，请告诉我
您已配置为打开'C：\ Users \ ramcharan.gottipati \ Desktop \ Task'作为文件，而我认为您应该提供文件名。
here字段是'报告定义文件'应该像“C：\ Users \ ramcharan.gottipati \ Desktop \ Task.prpt”如果你必须指定字段'输出文件'路径到结果pdf，如：“C：\ Users \ ramcharan.gottipati \桌面\ Task.pdf”
执行期间会发生什么？ PDI将使用pentaho报告处理器的输入数据流。报告（prpt）已经配置为使用与水壶输入流中的字段名称匹配的正确输入字段。名称和数据类型必须匹配，否则您可能会收到错误以处理报告。如果一切正常，使用此步骤类似于使用水壶输入运行pentaho报告引擎。即使没有水壶，任何人都可以运行pentaho报告引擎。
希望能帮助到你。
