   Hi everyone,
   
   We are seeing errors which _possibly_ originate from this code:
   
   `def write_mutate_metrics(self, rows):
       for status in rows:
         grpc_status_string = (
             ServiceCallMetric.bigtable_error_code_to_grpc_status_string(
                 status.code))
         self.service_call_metric.call(grpc_status_string)
   `
   
   Error message:
   `
   File "/usr/local/lib/python3.6/site-packages/apache_beam/io/gcp/bigtableio.py", line 123, in write_mutate_metrics status.code))
   AttributeError: 'NoneType' object has no attribute 'code' [while running 'Write event Bigtable row/ParDo(_BigTableWriteFn)-ptransform-58134']
   `
   
   Would you have any idea about this issue? 
   
   We are running
   
   - Python 3.6
   - Beam 2.35
   - GCP DataflowRunner
   
   In addition, the choice of parameter name (rows) is confusing. Perhaps something like responses or response_list ?

   https://googleapis.dev/python/bigtable/1.3.0/_modules/google/cloud/bigtable/table.html#Table.mutate_rows
   
   Thank you for your time.
   
   Regards
   Rashid
