connection.py:397, write_binary_str, 'NoneType' object has no attribute 'encode'

While I am testing the dbt plugin, I hit the issue in proton_driver/connection.py:397: in send_hello

/Users/jove/Dev/py310-dbt18-env/lib/python3.10/site-packages/proton_driver/connection.py:397: in send_hello

text = None, buf = <proton_driver.bufferedwriter.BufferedSocketWriter object at 0x121f2dcb0>

    def write_binary_str(text, buf):

I tried both Python 3.10 and 3.12, both 0.2.8 and 0.2.10. This can be reproduced with pytest --log-cli-level=DEBUG tests/functional/test_proton.py in the dbt-proton repo. But I will try to extract it and reproduce this without dbt.

The reason is the database can be None. In that case it fails call the encode method. Should check whether the text is none.
