访问自定义报告时，如何修复System.MissingMethodException：.ctor？

Question

在2019 R2中访问自定义报告时出现此错误：

使用完全相同的自定义项和报告，我可以在2019 R1上无错误地访问此报告。为什么我在R2上遇到此错误？

报表使用肥皂网络服务来获取数据。 PX.Data.Reports.SoapNavigator指向Web服务访问问题。

打开“ Web服务端点”屏幕SM207060，然后调用“查看端点服务”->“ WSDL”操作。

这应该以XML格式显示soap服务的WSDL接口。如果您在此处遇到错误，则意味着无法访问soap Web服务。这可能是由于许多原因。

首先检查您是否具有缺少实体的扩展端点，然后尝试在每个端点上打开WSDL。在还原快照并将端点声明包含在快照中而没有添加Web服务实体的自定义项时，可能会发生错误。

您可以在“端点名称”选择器中查看扩展实体。如果左侧实体树视图为空，则可能存在问题，您需要删除损坏的实体或发布其所需的自定义。
