Xuannan Su created FLINK-31944:
----------------------------------

             Summary: Protobuf format throw com.google.protobuf.InvalidProtocolBufferException
                 Key: FLINK-31944
                 URL: https://issues.apache.org/jira/browse/FLINK-31944
             Project: Flink
          Issue Type: Bug
          Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
    Affects Versions: 1.17.0
            Reporter: Xuannan Su
         Attachments: flink-protobuf-example.zip

It seems that protobuf format throws the following exception when the first field of the message is string type. This may also occur for other types. I uploaded the maven project to reproduce the problem.
