问根据streamid云点播合成报错？

我这里有个功能 根据直播streamid调用 concatMedia合成直播间回放视频时候 会报错

{"EventHandle":"8084501891639793477","EventType":"EditMediaComplete","EditMediaCompleteEvent":{"TaskId":"1256049057-EditMedia-7828db019d5fbaa197d4fda28ce76679t0","Status":"FINISH","ErrCode":70000,"Message":"internal error","Input":{"InputType":"Stream","FileInfoSet":[],"StreamInfoSet":[{"StreamId":"6eef1fef016eefb7b96fff808081006f","StartTime":"0000-00-00T00:00:00Z","EndTime":"0000-00-00T00:00:00Z"}]},"Output":{"FileType":"","FileId":"","FileUrl":""},"ProcedureTaskId":"","SessionContext":"","SessionId":""}}

过段时间再试，又成功了
