shashwatgaur commented on AVRO-2126: ------------------------------------ Hi, Any idea , why this issue([ avro.io.SchemaResolutionException: Can't access branch index 55 for union with 2 branches|https://stackoverflow.com/questions/62844195/kafka-python-avro-io-schemaresolutionexception-cant-access-branch-index-55-f]) happen?? Is it schema mismatch at reader's and writer's side or some data issue? What exactly? I am using kafka-python to read AVRO data and I am stuck with this issue. I already followed the thread [https://stackoverflow.com/questions/44407780/how-to-decode-deserialize-kafka-avro-strings-with-python] to skip 5 bytes but still no luck. Following is my code: {code:java} for message in consumer: message_val = message.value message_bytes = io.BytesIO(message_val[5:]) decoder = BinaryDecoder(message_bytes) event_dict = reader.read(decoder) print(event_dict){code} Thanks, > avro.io.SchemaResolutionException: Can't access branch index 36 for union > with 2 branches > ----------------------------------------------------------------------------------------- > > Key: AVRO-2126 > URL: https://issues.apache.org/jira/browse/AVRO-2126 > Project: Apache Avro > Issue Type: Bug > Components: python > Affects Versions: 1.8.2 > Environment: Python 3.5.2, avro-python3 1.8.2 > Reporter: Jurgis Pods > Priority: Major > > I get the following error when decoding messages from Kafka via avro-python3: > {code} > avro.io.SchemaResolutionException: Can't access branch index 36 for union > with 2 branches > Writer's Schema: [ > "null", > "string" > ] > Reader's Schema: [ > "null", > "string" > ] > {code} > Relevant code producing this error: > {code} > import avro.schema > import avro.io > import io > def parse_avro(value, schema): > bytes_reader = io.BytesIO(value) > decoder = avro.io.BinaryDecoder(bytes_reader) > reader = avro.io.DatumReader(schema) > return reader.read(decoder) > # msg: Message from Kafka, schema: avro.schema.Schema from Confluent Schema > Registry > parse_avro(msg.value, avro_schema) > {code} > I have no idea where the number 36 might come from. -- This message was sent by Atlassian Jira (v8.3.4#803005)
