So,
I\'m using the automated logging from AWS Lambda. It generates log streams with names that look like this: 2016/05/18/[$LATEST]99577d10a8cb420cb124a90c20d5653
2016/05/18/[$LATEST]99577d10a8cb420cb124a90c20d5653
Immediately after posting this I figured it out... The $ in [$LATEST] needs to be escaped... So it should look something like [\$LATEST].
$
[$LATEST]
[\$LATEST]
