I have exported the azure cost data to the storage account in parquet format. while parsing that file getting data output as GenericData$Fixed in bytes. I don’t know how to get the original value from this.

I tried toString() that also returns the same. Tried BigInteger that also not works

The data type is org.apache.avro.generic.GenericData$Fixed
My code is

ParquetReader<GenericRecord> reader = null;
        InputStream in = null;
        
        try
        {
            in = new FileInputStream(new File("part_1_0001.parquet"));
            
            ParquetStream parquetStream = new ParquetStream(String.valueOf(System.currentTimeMillis()), in);
            
            ParquetConfiguration conf = new PlainParquetConfiguration();
            conf.set(org.apache.parquet.avro.AvroReadSupport.READ_INT96_AS_FIXED, "true");
            
            reader = AvroParquetReader
                    .<GenericRecord>builder(parquetStream,conf)
                    .build();

            GenericRecord record;
            
            while ((record = reader.read()) != null) 
            {
                Object fieldValue = record.get(42); 
              // fieldValueOutput - [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 88, 121, -61, -40, 0]
                
            }
                    
        }
        catch(Exception e)
        {
...
        }
        finally
        {
            if(reader != null)
            {
                try
                {
                    reader.close();
                }
                catch(Exception e)
                {
                    ...
                }
            }
            if(in!=null)
            {
                try
                {
                    in.close(); 
                }
                catch(Exception e)
                {
                    ...
                }
            }
        }
    ```

Anyone guide me to get the original value from this.
