Thank you for the issue report @mbejda

This looks a lot like a server/driver version mismatch. The versions you mention seem fine though. Did you update rethinkdbdash to the latest version as well?

Ping @neumino

[neumino]

Looking at the log, you are using thinky, which uses rethinkdbdash.
Can you run npm install thinky in /app/production?

[neumino]

I think this error can happen with rethinkdbdash < 1.13.7 when the versions (driver - server) were not matching.

Hi @mbejda ! This is almost certainly a server/driver mismatch like @danielmewes said. Closing, but please re-open if the server and driver versions match and you still get this error.
