I'm using Gremlin Console to open a .gryo file but am getting this puzzling exception:
org.apache.tinkerpop.shaded.kryo.KryoException: Buffer underflow
org.apache.tinkerpop.shaded.kryo.KryoException: Buffer underflow
Can anyone help me understand how to get past it? Or understand what to look for to prevent it?
Dave
The full stacktrace is:

not exactly sure but that usually means kryo has encountered an unexpected type or like unexpected bytes for a particular type it thinks it needs to deserialize. are there custom types in that file that you know of? something outside of those registered here:
Or maybe your Gryo file was created in one version of TinkerPop and you are trying to open in another? it's rare for there to be compatibility issues there but i suppose it's possible.

Thanks for those suggestions. After looking into it with those things in mind, I theorized that the file had become corrupted in some way. I ran the program that generated it, and the new .gryo file loads fine.
It was useful knowing that the error was uncommon.
Thanks
Dave
