Any chance you dropped a parent VDS and renamed a child VDS as the parent VDS name? We have a similar bug and currently working on fixing it
Thanks
@balaji.ramaswamy
There was not issue in creating VDS from Orignal source ,only issue if i enable Reflection On Created Virtual Data set which had same name which i have been deleted then i get this Error,else i can able to query witout reflection too.
I am still not able to solve Stack Over flow Error,even If i Deleted Orignal Source,Delete DataSet ,and all spaces,
connected New Source,Created Same DataSet Space name as it was old but when i am creating dataset from new Source still job count ,metadata attached to that DataSet may i know the reason…
what is solution for that,
if i give Diffrent name from Previuos DataSet it will Preview Sucessfully with any errors
@balaji.ramaswamy ,i have followed your procedure it seems it works for few days but again its throwing stackOverFlow Error,this time i did not even enable Reflection ,
I see your comment as its a bug may i know which is the fixed version …
