Avro.AvroException: Unable to find type 'example.test.value' when Namespace isn't 'example.test.value'

See original GitHub issue

Description

Confluent.Kafka nuget version = 1.7.0 and 1.8.2 Confluent.SchemaRegistry Version=1.7.0 1.8.2 Confluent.SchemaRegistry.Serdes.Avro Version= 1.7.0 and 1.8.2 Apache Kafka version = 2.8.0 No Critical issue

ERROR xxxx - Kafka1 | Error while consuming from topics Confluent.Kafka.ConsumeException: Local: Value deserialization error —> Avro.AvroException: Unable to find type ‘example.test.value’ in all loaded assemblies at Avro.Specific.ObjectCreator.<>c__DisplayClass14_0.<FindType>b__0(String _) at System.Collections.Concurrent.ConcurrentDictionary2.GetOrAdd(TKey key, Func2 valueFactory) at Avro.Specific.ObjectCreator.GetType(String name, Type schemaType) at Avro.Specific.SpecificDefaultReader.ReadRecord(Object reuse, RecordSchema writerSchema, Schema readerSchema, Decoder dec) at Avro.Generic.DefaultReader.Read[T](T reuse, Decoder decoder) at Confluent.SchemaRegistry.Serdes.SpecificDeserializerImpl1.Deserialize(String topic, Byte[] array) at Confluent.SchemaRegistry.Serdes.AvroDeserializer1.DeserializeAsync(ReadOnlyMemory1 data, Boolean isNull, SerializationContext context) at Confluent.Kafka.SyncOverAsync.SyncOverAsyncDeserializer1.Deserialize(ReadOnlySpan1 data, Boolean isNull, SerializationContext context) at Confluent.Kafka.Consumer2.Consume(Int32 millisecondsTimeout) — End of inner exception stack trace — at Confluent.Kafka.Consumer2.Consume(Int32 millisecondsTimeout) at Confluent.Kafka.Consumer2.Consume(TimeSpan timeout)

This Error comes when consuming Avro Data from a Topic.

This error only comes when the C# namespace in that is the Avro Class isn’t “example.test.value”

When changing the namespace of the class to example.test.value the error is fixed.

I want that i can use the example.test.value Schema in a Namespace that isn’t example.test.value.

Is that possible?
