Hey!

In case you did not resolve this issue (or somebody struggles with the same problem): I stumbled upon a similiar error message when trying to start several workers on a Cluster.

It turned out that I somehow updated 'some' NuGet-packages to Akka.[SomeSubPackage].1.3.1 and some were still on Version 1.2.3. After resetting them to the last configuration that I knew was working (i.e. v1.2.3), the problem was gone.

Hope this helps!

Without specifying which version of Akka is being used. Helping with this issue is impractical. Especially since in recent releases we solved many serialiser related issues. Im going to close this issue. @virenderkverma If you still have this problem after updating to the last akka.net version. And making sure your lighthouse instance is running on the same akka.net version as your worker nodes. Feel free to open it again.
