rethinkdb.errors.ReqlDriverError: Unexpected response received.

[tatiblockchain]

I have been struggling with this issue for a while, i have searched online and have not come across any solution. The closest issue to this one - which presented no solution online is this one.

I am running rethinkdb on Python 2.7 on Ubuntu 16. Everything works fine in development, i tried all the tables in development and no issue. But when i introduce wsgi - i start experiencing this error - intermittently. So sometimes it works, sometimes it does not - its quite random, i am never sure when the error will happen. When it does, it happens on random routes, and functions.

This is the full error message - on one route.

Hello @tatiblockchain,

Thanks for opening this issue. Could you please help me by providing more info about the environment? You wrote that when you develop everything goes well, but when you introduce WSGI the driver is acting weird.

Are you introducing that WSGI locally or is that on a production/public facing server? As I can see in https://github.com/rethinkdb/rethinkdb-python/blob/master/rethinkdb/net.py#L613-L615 this error should be raised if the response is corrupted or not intended for us.

Which version of RethinkDB are you using? Which driver version? Could you please help with other non-sensitive details as well like where the issue happens (locally or a production env for example)?
