Redis::CommandError at /search #11

Redis::CommandError at /search ERR wrong number of arguments for 'mget' command

After following the setup/installation I wind up getting this message in the web interface and thin log. It appears that an empty array is being passed to the redis function mget, however I am not sure exactly why. Any help would be much appreciated. Ruby version 1.9.3-p448 (rvm)

@aaronpsamuel I've been looking into this and haven't been able to reproduce it yet. Will keep at it though!

@aaronpsamuel couple of questions for you to try and dig into this a little further:

Do you have any data in your Skyline redis instance?
Has any data been imported into the Oculus Elasticsearch indexes?

I'm wondering if this is a bug with a totally virgin install that I missed - ie if there is literally no data in ES or Skyline.

@jonlives -

Do you have any data in your Skyline redis instance?
- Yes i was able to confirm the data within the redis instance by querying the keys. I see the horizon UDP tests within the output.
Has any data been imported into the Oculus Elasticsearch indexes?
- I believe so. I was able to run the import script with no obvious error, and when going to initialize collections no errors are reported.

This has been fixed now - it was an issue with trying to fetch results from redis when there was nothing to fetch.
