log(level, message, category="default")
Log a message in the logging queue. It is often difficult to see output
of a trigger unless you are running the server in debug mode. In
production mode, the server sends the output to log files which
are general buffered, so it cannot be predicted exactly when
this output will be dumped to a file.
This method will make a request to the server and store the message
in the database in the debug log table.
level - debug level
message - freeform string describing the entry
category - a label for the type of message being logged.
It defaults to "default"
