Janusgraph 1.0.0 Export and Import

[angu2015]

Janusgraph Export and Import using GyroWriter.writeGraph is exporting successfully but while import it throws Missing VertexID. Any other method to export as whole graph in binary form? I am using janusgraph 1.0.0

Could you please provide the full stacktrace?

This may or may not have been fixed by https://github.com/JanusGraph/janusgraph/pull/4278/files. Anyways, it's worth trying the "unreleased" version. If you use JanusGraph as a library we do publish a version for every commit on main.

I tried the unreleased version it's working now. the export and import of graph using gyro is working as expected. I am not using it as library. I did a unit test by building the master branch and generated the zip and run it as a server. Thanks for helping me.

The same issue occurred for ConfigurationManagementGraph. Here is the trace of Error log

Any update on this. @li-boxuan

Can you try a hack and see if it works?
