我在Azure数据工厂中设置了一个相对简单的过程来复制，清理和处理来自聊天机器人的一些日志文件，该聊天机器人一直运行良好，直到我最近开始收到以下错误代码：
"errorCode": "InvalidTemplate",
"message": "Unable to process expressions for action 'EvaluatefinaliseTSCRPTS': 'The function 'bool' was invoked with a parameter that is not valid. The value cannot be converted to the target type",
"failureType": "UserError",
"target": "finaliseTSCRPTS",
"details": ""
尽管经历了以下过程的代码，但我似乎无法识别ADF过程中的错误：

没有表达式“ EvaluatefinaliseTSCRPTS”，我也找不到“布尔”函数。我发现的唯一提示是上一个问题here
答案 0 :(得分：0)
您有一个名为“ finaliseTSCRPTS”的IF活动，因此“ EvaluatefinaliseTSCRPTS”很可能是执行IF条件检查的函数的内部名称。该消息似乎表明它无法评估您的表达式“ activity（'MST Validation'）。output.exists”。
