Hi,
We are getting the below error when trying to connect to cassandra database using liquibase version, 3.10.3 and liquibase cassandra ext, 4.3.1.

Hi @Gotham333 ,

Could we see the complete stacktrace? Also have you tried using the same version of extension as your core liquibase version (3.10.3), does the error happen then also?
