NullPointerException at FeedCli.java llne 300

[FreeGoldRush]

I'm getting this:

16:30:47.433 [main] DEBUG com.ebay.feed.auth.CredentialLoader - ****** Begin getOauthResponse with configPath = /home/mike/cards/FeedSDK/credentials.yaml
Exception in thread "main" java.lang.NullPointerException
at com.ebay.feed.cli.FeedCli.start(FeedCli.java:300)
at com.ebay.feed.cli.FeedCli.main(FeedCli.java:278)

The appid, certid and devid are correct in the config file and are my production values. The redirecturi I don't completely understand. I'm using the "RuName" in the section of my account called "Get a token from eBay via Your Application". It's in the box in the top left corner under "RuName (eBay Redirect URL name)". Is this the correct value for the config field called "redirecturi"? If not, then where do I get the value for "redirecturi"? Is there anything else that could be creating this exception?

Thank you.
