<PackageReference Include="Confluent.Kafka" Version="2.2.0" />
<PackageReference Include="Confluent.SchemaRegistry" Version="2.2.0" />
<PackageReference Include="Confluent.SchemaRegistry.Serdes.Json" Version="2.2.0" />

using var producer = new ProducerBuilder<string, TValue>(producerConfig)
            .SetKeySerializer(Serializers.Utf8) // same issue with or without this line
            .SetValueSerializer(new JsonSerializer<TValue>(schemaRegistry))
            .Build();

Steps to reproduce

• Produce a message on topic X, with the configuration above
• Producer auto create subject X-value in schema registry
• Message is produced
• On Kafka UI, create a message on topic 'X'
