Debezium connector error for source cassandra

Question

I installed debezium 2.4, cassandra 3.11.9 and kafka latest with dockerize. My cassandra table:

cqlsh> desc test.foo;

CREATE TABLE test.foo (
     a int PRIMARY KEY,
     b text
) WITH bloom_filter_fp_chance = 0.01
     AND caching = {'keys': 'ALL', 'rows_per_partition': 'NONE'}
     AND cdc = true

I entered my debezium container with bash.

=>> docker exec -it source-debezium-1 /bin/bash

I created the "debezium-connector-cassandra" file in the /kafka/connect directory and created the "debezium-cassandra-connector.properties" file inside. my debezium-cassandra-connector.properties:

enter image description here

Then I ran the following command.

  java -jar /kafka/connect/debezium-connector-cassandra/debezium-connector-cassandra-1.1.1.Final-jar-with-dependencies.jar /kafka/connect/debezium-connector-cassandra/debezium-cassandra-connector. properties > debezium.stdout.log 2> debezium.stderr.log

and I get the following error:

  [kafka@57ccaff8016f ~]$ cat debezium.stderr.log

can you support me?

I checked my cassandra container. cassandra.yaml location is correct. I made the necessary configurations, but my connector is not working.
