How to setup and configure mongodb kafka soruce connector using aws msk connect?

I have setup a MSK cluster using public subnets. I also have turned on public access for this MSK cluster. The cluster is up and running. I am trying to setup MongoDB Kafka Source Connector using MSK connect. I have selected IAM authentication and created IAM Role and corresponding policy for authentication. Below is my mongodb kafka source connector configuration

connector.class=com.mongodb.kafka.connect.MongoSourceConnectortasks.max=1connection.uri=mongodb+srv://XXXXX:XXXXXXX@XXXXXXX.qricz.mongodb.net/user?authSource=admin&replicaSet=atlas-bftscy-shard-0&readPreference=primarydatabase=usertopic.prefix=mongopoll.max.batch.size=1000poll.await.time.ms=5000pipeline=[]batch.size=0publish.full.document.only=truemongo.errors.tolerance=allmongo.errors.deadletterqueue.topic.name=data-ingestion-dlq-betaoffset.partition.name=mongodb-source-connector-beta.1startup.mode=copy_existingoutput.format.value=jsonoutput.format.key=jsonkey.converter.schemas.enable=falsevalue.converter.schemas.enable=falsekey.converter=org.apache.kafka.connect.storage.StringConvertervalue.converter=org.apache.kafka.connect.storage.StringConverterchange.stream.full.document=updateLookup

But when I am creating the connector it's getting failed due to the following error
