[karo_lina]

Hi, I have experenced an unexpected DataFlow refresh error. Some of my dataflows finished scheduled refresh with an errror. 

I tried to refresh them manualy and it worked for most of them. Except the one which is failing inspite of few manual refresh atepmts.  

Does enyone have experienced this same issue. What can I do to avoid it within nex scheduled refresh? Error description below. 

Error: PipelineException: Operation is not valid due to the current state of the object. 

RootActivityId = 5d32bd4e-eaf0-4cfb-b41c-41bcac3163e2.Param1

Hi @v-kelly-msft ,

Thank you for your message. All the sources used in this particular data flow are SharePoint lists. There are 30 of them in total. After a few days, they returned to normal functioning. This is a very strange behavior and I cannot understand why it happened. For me it is necessary to ensure constant access for users.

Hi @karo_lina ,

Not quite sure,maybe it's a conflict from network or a temporary bug which has been solved now.

Once you find the issue again,welcome to be back to me.

Best Regards,
Kelly

Hi  @karo_lina ,

Such error message usually means the file is corrupted,so pls check whether the source file is OK.
