The gateway did not receive a response from 'Microsoft.DataFactory' within the specified time period.

Hello,

This is currently happening in Azure Data Factory. I'm trying to use the 'Data Peview' option in one of my dataflows, but I'm getting the following error instead:

112555-screenshot-from-2021-07-07-15-07-05.png



The pipeline runs though, and also in different branches this feature is working without any problems. How can I debug this?

Hi @FranciscoDominguez-7929 ,

Welcome to Microsoft Q&A Platform. Thank you for posting your query.

It looks like intermittent issue. Could you please try to restart your debug session and see.

Also, kindly try to data preview at source transformation first to check everything is fine there or not.

Hope this helps. Thank you.

Hi @ShaikMaheer-MSFT ,

Yeah, that's usually the workaround but, even after you restart the debug session, after a few tries it stops working again.

And yes, I've tried in all the stages of the data flow and the error is always the same.


Regards.

HI @FranciscoDominguez-7929 ,

Thanks and glad to know that debug restart helped you. Please Accept Answer. Accepting answer helps community.

Regarding follow-up query, Could you please help on below queries.

  • How frequently you are observing this issue? I mean what is the time interval?

  • Debug sessions will have time to live setting, Did you tried increasing that time to live setting value?

Please Note, If you leave your session idle without any data preview more than time to live value and then try to data preview then you may see this kind of intermittent issue.

You might be trying to load a very huge amount of data ! I had the same issue. I did get rid of few of the data and it worked fine without making any changes or restarting debug session.
