We're seeing an issue in our production environment. It happens pretty inconsistently, so I'm not sure of how exactly to reproduce it. The error message and stack:

The error seems can not be caught. I wrapped try-catch on all of my spanner operations but still got restart of my nodejs process.
Please let me know what other information would be helpful.
