The problem was incompatibility with cassandra, which accepts bool as a string in `fromJson()` UDF. The difference between Cassandra and Scylla now is Scylla accepts whitespaces around word in string, Cassandra don't. Both are case insensitive. Fixes: https://github.com/scylladb/scylla/issues/7915 Closes #10134 * github.com:scylladb/scylla: CQL3/pytest: Updating test_json CQL3: fromJson accepts string as bool
