> Not sure if this is the absolute minimal case that produces the bug, but here are the steps for reproducing.
> 1. Create table
> {code}
> CREATE TABLE test (
> id text,
> ck1 text,
> ck2 text,
> static_value text static,
> set_value set<text>,
> primary key (id, ck1, ck2)
> );
> {code}
> 2. Create secondary indices on the clustering columns, static column, and collection column
> {code}
> create index on test (set_value);
> create index on test (static_value);
> create index on test (ck1);
> create index on test (ck2);
> {code}
> 3. Insert a null value into the `set_value` column
> {code}
> insert into test (id, ck1, ck2, static_value, set_value) values ('id', 'key1', 'key2', 'static', {'one', 'two'} );
> {code}
> Sanity check: 
> {code}
> select * from test;
>  id | ck1  | ck2  | static_value | set_value
> ----+------+------+--------------+----------------
>  id | key1 | key2 |       static | {'one', 'two'}
> {code}
> 4. Set the set_value to be empty
> {code}
> update test set set_value = {} where id = 'id' and ck1 = 'key1' and ck2 = 'key2';
> {code}
> 5. Make a select query that uses `CONTAINS` in the `set_value` column
> {code}
> select * from test where ck2 = 'key2' and static_value = 'static' and set_value contains 'one' allow filtering;
> {code}
> Here we get a ReadFailure:
> {code}
> ReadFailure: Error from server: code=1300 [Replica(s) failed to execute read] message="Operation failed - received 0 responses and 1 failures" info={'failures': 1, 'received_responses': 0, 'required_responses': 1, 'consistency': 'ONE'}
> {code}
> Logs show a NullPointerException
