Review Comment:

In Python versions prior to 3.10, `traceback.format_exception` does not
accept a single exception object as a positional argument and will raise a
`TypeError` (missing `value` and `tb` arguments). Since Apache Beam supports
Python 3.8 and 3.9, you should pass `type(exception), exception,
exception.__traceback__` to maintain backward compatibility.
```python
tb_str = "".join(
traceback.format_exception(
type(exception), exception, exception.__traceback__))
```
