Apache Beam Python: How to fix field schema decoding error from ReadFromJDBC + Postgres

I have a postgres table with schema

row_id      INT not null
person_id   INT not null
case_id     INT not null
seq_num     INT 
code        VARCHAR(10)

The test pipeline to read the data using ReadFromJDBC from Apache Beam Python sdk (2.34.0), Python 3.8.x

types = [
    ('row_id', int), ('person_id', int), ('case_id', int), ('seq_num', int), ('code', str)
]

TableRow = typing.NamedTuple('TableRow', types)

with TestPipeline() as p:
    coders.registry.register_coder(TableRow, coders.RowCoder)
    
    p.not_use_test_runner_api = True  
    result = (
      p
      | 'Read from jdbc' >> ReadFromJdbc(
          table_name=table_name,
          query='SELECT * FROM table_name LIMIT 100',
          driver_class_name='org.postgresql.Driver',
          jdbc_url=postgres_jdbc_url,
          username=username,
          password=password,
      ))

is giving me the following error

I am having trouble understanding what should I do to fix it. It seems like Apache Beam doesn't know how to decode VARCHAR(10) into string. What is the correct schema to use? Or what else should I do?
