In file: "CSharpClient-for-Kafka/src/KafkaNET.Library/Consumers/PartitionLeaderFinder.cs" on line 80 when making the creating a TopicMetadataRequest to get consumer metadata, a hard coded value of 1 is passed in as the versionId:
IEnumerable<TopicMetadata> metaData = consumer.GetMetaData(TopicMetadataRequest.Create(new[] { partition.Topic }, 1, 0, clientId));
Looking at other instances of VersionId used in other classes, seems like this should be set to 0.
Having it set to 1 causes the partition not finding a leader and results in the following exception, which fails silently:
