Dataflow created correctly but fails first refresh "Unable to cast object of type 'System.Net.HttpWe
Hi bugs84 ,
It seems that this is an object conversion error. Which data source you are using for creating the dataflow? Is there any change to this underlying data source after created this dataflow? And could you please try to re-create this dataflow with same operations and refresh it? Later check whether it still refresh fails...
In addition, please review the following documentations and hope they can help you.
Best Regards
Rena
Hello Rena,
unfortunately my dataflow is -apparently randomly- not refreshing anymore:
As you can see in the above screenshot, my dataflow sometimes fails (always the same error), but then I ask for a manual refresh and it works.. and then maybe the next refresh is not working anymore - and I did not do anything in the time between.
Therefore I ask once more for some help. I try to answer your questions:
Which data source you are using for creating the dataflow? >> Oracle database
Is there any change to this underlying data source after created this dataflow? >> No
And could you please try to re-create this dataflow with same operations and refresh it? >> I did it (this is the 2nd dataflow): at first it worked, now is working randomly.
I also checked the linked documentation, but it seems not really pertinent to my situation (given the fact that, apparently, I am refreshing or not without any changes from my side).
I hope you or someone can help us.
Thanks in advance
