Review Comment:
Looks like this was using ```rowcoder``` and the element type was as
expected. The error itself is being thrown from
[here](https://github.com/svetakvsundhar/beam/blob/bqio/sdks/python/apache_beam/coders/coders.py#L864),
could this be because of the protocol being used? I tried using
```DEFAULT_PROTOCOL```, but that didn't seem to work..I'll take this up and
check at intermediate points if rowcoder is behaving the way we expect.
