Any idea what could be the solution!

Answer 1

Finally, I got the solution, This issue was happening because I was not finding the exact saga to update the sagadata instance. Somehow, it was grabbing some other instance of saga and trying to update it which doesnot belong to the correct resourcemanagerid of ravendb and it was throwing exception.
When I resolved the saga correctly then it got resolved.
Thanks everyone for your time.

Answer 2

I know this is a old post, but I was facing the same error recently and this post is the one that you'd find first when you google.
This problem occurred after I deleted the Raven Resource in Raven Studio while keeping the files on disk. I had to delete the resource again with the Delete option: "Delete everything" on.
SideNote: This was in my development environment, I'd probably would be more careful in a production environment.
