      Bug report

      For bug reports, provide this information, please:

      What Debezium connector do you use and what version?

      debezium-connector-mongodb-2.0.0.Final

      What is the connector configuration? 

      class: io.debezium.connector.mongodb.MongoDbConnector config: mongodb.hosts: > psmdb-db-entity-mongos-0.psmdb-db-entity.svc.cluster.local, psmdb-db-entity-mongos-1.psmdb-db-entity.svc.cluster.local mongodb.name: entity topic.prefix: entity mongodb.user: <user> mongodb.password: <password> mongodb.authsource: admin database.include.list: > PaymentEntities, debezium signal.data.collection: debezium.debeziumSignal collection.exclude.list: > .+.system.profile snapshot.max.threads: 2 schema.name.adjustment.mode: avro key.converter: io.confluent.connect.avro.AvroConverter key.converter.schema.registry.url: <URL> value.converter: io.confluent.connect.avro.AvroConverter value.converter.schema.registry.url:<URL>

       

      What is the captured database version and mode of depoyment?

      The connector is deployed on Kubernetes using KafkaConnector CRD from strimzi operator version 0.32.0

       

      What behaviour do you expect?

      I'm trying to enable incremental snapshots, and I'm expecting the connector to start the ad-hoc snapshot

      What behaviour do you see?

      I'm receiving an error once I send the signal to start the ad-hoc snapshot, 

      Do you see the same behaviour using the latest relesead Debezium version?

      (Ideally, also verify with latest Alpha/Beta/CR version)

      I have verified this error on 2.0.0 and I will try to test on latest Alpha

      Do you have the connector logs, ideally from start till finish?

      How to reproduce the issue using our tutorial deployment?

      Use this command to trigger an ad-hoc snapshot

      db.debeziumSignal.insertOne({
          "type" : "execute-snapshot",
          "data" : {
          "data-collections": ["PaymentEntities.Entities"],
          "type": "incremental"}
          });
