Kafka connect failing to create Mongo Source Connector - mongodb

Question

I'm getting an error while creating a source connector. It works fine in all the environments except one place. I'm using a mongodb user having read-write permission which has all the actions changeStream and find. But still I'm getting this error. Also this is not present in /connector-plugins/{connectorType}/config/validate though.
Config:
{
"name": "mongo-source",
"config": {
"connector.class": "com.mongodb.kafka.connect.MongoSourceConnector",
"pipeline": "{{pipeline}}", //variable replaced appropriate value
"transforms.dropPrefix.replacement": "{{topic}}", //variable replaced appropriate value
"topic.prefix": "",
"tasks.max": "1",
"poll.await.time.ms": 5,
"connection.uri": "${file:/secrets/secrets.properties:mongo.connection.uri}",
"transforms": "dropPrefix",
"change.stream.full.document": "updateLookup",
"errors.tolerance": "none",
"transforms.dropPrefix.regex": ".*",
"transforms.dropPrefix.type": "org.apache.kafka.connect.transforms.RegexRouter"
}
}
ERROR
{
"error_code": 400,
"message": "Connector configuration is invalid and contains the following 1 error(s):\nInvalid user permissions. Missing the following action permissions: changeStream, find\nYou can also find the above list of errors at the endpoint `/connector-plugins/{connectorType}/config/validate`"
}

You have to try /connector-plugins/{connectorType}/config/validate with config value in data:
{
"connector.class": "com.mongodb.kafka.connect.MongoSourceConnector",
"pipeline": "{{pipeline}}", //variable replaced appropriate value
"transforms.dropPrefix.replacement": "{{topic}}", //variable replaced appropriate value
"topic.prefix": "",
"tasks.max": "1",
"poll.await.time.ms": 5,
"connection.uri": "${file:/secrets/secrets.properties:mongo.connection.uri}",
"transforms": "dropPrefix",
"change.stream.full.document": "updateLookup",
"errors.tolerance": "none",
"transforms.dropPrefix.regex": ".*",
"transforms.dropPrefix.type": "org.apache.kafka.connect.transforms.RegexRouter"
}
P.S.: At least you need a field "name" inside config value.
