Thanks for the pointers Andrey, they helped us zero in on the issue.
We found that it was a bug in our Scala code that caused Flink to use Kryo

We've fixed it, and are able to evolve state-schema seamlessly now.

Hi Daksh,
You need to find which type causes the problem: Long, MyCustomObject or

My guess is that your scala code uses another serializer for the failing
type. See also docs to understand serialization in Flink [1]
