Azure data factory 从管道传递到链接服务baseURL的NULL
我有一个管道，可以迭代文件并将它们复制到存储位置 baseURL和relativeURL存储在json文件中 我可以读入这个文件，它是有效的 我已经参数化了链接的服务baseURL，当从链接的服务和数据集进行测试时，这会起作用 但是，当我尝试调试管道时，出现了一个错误： “代码”：“BadRequest”Azure data factory 从管道传递到链接服务baseURL的NULL,azure-data-factory,azure-data-factory-2,azure-data-factory-pipeline,Azure Data Factory,Azure Data Factory 2,Azure Data Factory Pipeline,我有一个管道，可以迭代文件并将它们复制到存储位置 baseURL和relativeURL存储在json文件中 我可以读入这个文件，它是有效的 我已经参数化了链接的服务baseURL，当从链接的服务和数据集进行测试时，这会起作用 但是，当我尝试调试管道时，出现了一个错误： “代码”：“BadRequest” “消息”：空 “目标”：“管道//runid/310b8ac1-2ce6-4c7c-a1ad-433ee9019e9b” “详细信息”：空 “错误”：空 从管道中的活动中，似乎传递的是空值，而
