Presto unable to create injector with localfile connector

I am using presto-server-0.149 on macOS 10.11. Just for testing purpose, I run a single node and everything is okay. When I add etc/catalog/localfile.properties with:

connector.name=localfile
presto-logs.http-request-log-location=/var/log/apache2/access_log

I get the following error:

UPDATE

Based on Dain Sundstrom's answer below, I was able to fix my problem. It turned out that the fb documentation for Local File Connector is incorrect. And since I needed to get something to feed Presto to test the localfile connector, I changed the config filepath to Presto's own request log: 

presto-logs.http-request-log.location=/var/presto/data/var/log/http-request.log

You have a typo in the configuration property. It should be:

presto-logs.http-request-log.location=/var/log/apache2/access_log

Also, this connector can only process the http log format created by Presto itself, so you would need to reconfigure your Apache2 server to output the same format.
