Exceptions while writing to log

[hzawawy]

During the syzkaller runs, we get a lot of these exceptions. They dont stop the run though. Traceback (most recent call last): File "/usr/local/lib/python3.7/logging/handlers.py", line 631, in emit s = self.makePickle(record) File "/home/shell/clusterfuzz/89JAX004UK/bot/clusterfuzz/src/python/metrics/logs.py", line 226, in makePickle return (format_record(record) + '\n').encode('utf-8') File "/home/shell/clusterfuzz/89JAX004UK/bot/clusterfuzz/src/python/metrics/logs.py", line 184, in format_record return json.dumps(entry) File "/usr/local/lib/python3.7/json/init.py", line 231, in dumps return _default_encoder.encode(obj) File "/usr/local/lib/python3.7/json/encoder.py", line 199, in encode chunks = self.iterencode(o, _one_shot=True) File "/usr/local/lib/python3.7/json/encoder.py", line 257, in iterencode return _iterencode(o, 0) File "/usr/local/lib/python3.7/json/encoder.py", line 179, in default raise TypeError(f'Object of type {o.class.name} ' TypeError: Object of type bytes is not JSON serializable

So, this is just failure to log things since some message in log is not serializable. Do you log any output from logs.log, can try removing that and seeing if this goes away.

This is not a major just littering the logs. I will investigate further and prepare a fix.
