Cassandra query runner not working in docker

I’ve added REDASH_ADDITIONAL_QUERY_RUNNERS: "redash.query_runner.cass" to my docker-compose.yml and cassandra appears as a valid type of data source in the UI, testing the connection succeeds, and the query editor can see my schema. However, when I go to actually execute a query, the query (any query) fails with: ` worker_1 | [2017-11-08 23:39:12,363][PID:1][ERROR][MainProcess] Task redash.tasks.execute_query[d26f4030-53e2-4556-8ff5-95c74912c2bb] raised unexpected: AttributeError(“‘NoneType’ object has no attribute ‘annotate_query’”,)

is there any additional configuration needed besides REDASH_ADDITIONAL_QUERY_RUNNERS: "redash.query_runner.cass" to make cassandra work properly?

@RichardLitt Sorry for the confusion, I was solving my own question below the divider. I will edit it to make it more obvious.

I have some problem too with Cassandra Driver in the docker redash version. I added the env REDASH_ADDITIONAL_QUERY_RUNNERS: “redash.query_runner.cass” and I can see it inside the containers but I am unable to connect to Cassandra from Redash. Any ideas?
