Value deserialization error: Method not found..

Description

I am using consumer with schema registry to consume Avro data. I am using AvroDeserializer to desrialize the data. It was working fine and suddenly it started showing this error:

InnerException = {"Method not found: 'System.Threading.Tasks.Task1<System.String> Confluent.SchemaRegistry.ISchemaRegistryClient.GetSchemaAsync(Int32)'."}

Message = “Local: Value deserialization error”

StackTrace = " at Confluent.Kafka.Consumer2.Consume(Int32 millisecondsTimeout)\r\n at Confluent.Kafka.Consumer2.Consume(CancellationToken cancellationToken)\r\n `

This my consumer: ` using (var schemaRegistry = new CachedSchemaRegistryClient(schemaRegistryConfig)) using (var consumer = new ConsumerBuilder<string, Order>(consumerConfig) .SetValueDeserializer(new AvroDeserializer<Order>(schemaRegistry).AsSyncOverAsync()) .SetErrorHandler((_, e) => Console.WriteLine($“Error: {e.Reason}”)) .Build()) { consumer.Subscribe(“topic”);

            try
            {
                while (true)
                {
                    try
                    {
                        var consumeResult = consumer.Consume(cts.Token);
                        Console.WriteLine(consumeResult.Value.ToString());
                    }
                    catch (ConsumeException e)
                    {
                        Console.WriteLine($"Consume error: {e.Error.Reason}");
                    }
                }
            }
            catch (OperationCanceledException)
            {
                consumer.Close();
            }
        }`

https://www.nuget.org/packages/Confluent.SchemaRegistry.Serdes.Avro/

Confluent.SchemaRegistry 1.4 and Confluent.SchemaRegistry.Serdes 1.3 are not compatible - the error you are seeing is expected.

@mhowlett Thanks, everything works fine now. I will close the issue since it is solved. Using Confluent.SchemaRegistry.Serdes.Avro insted of Confluent.SchemaRegistry.Serdes solved the problem.
