KeyError while logging

[pavelschon]

I've got an unexpected error when trying to log a formatted dictionary:

$ python
Python 3.9.7 (default, Jun  1 2022, 14:59:30)

>>> log = txaio.make_logger()
>>> log.info(str({"hello": "world"}))
Traceback (most recent call last):

KeyError: "'hello'"

The structured logger here takes a "format string" as the first argument .. and those format strings use { and } characters. So e.g. try log.info("{foo}", foo={"hello": "world"}) or similar.

Thanks, so this is a user issue then.
