I've been trying to set up a CKAN installation for use as a Caribbean open data portal for a few weeks now but I've been running into challenges when I try to set up the CKAN Harvester and import some data sets. More specifically, I'm running into two specific errors.
1) The Harvester does not work unless I start the gather and fetch queues manually in the command line. If I don't do that, I get a simple error when I try to run the harvester on a data source from the front-end.
An error occurred: [2.0]
2) Like I said, I've been able to work around this error by starting those queues via the terminal but I'm guessing that isn't how it's supposed to work (I shouldn't need to do that right?). The second issue occurs when I resolve the first one and has to do with me trying to set the "default_groups" parameter.
If I set it to an empty set like so --> "default_groups" : 
There are no issues.
But if I try to include groups like so ---> "default_groups" : ["trinidad"]
I get this error :
The form contains invalid entries:
Config: Error parsing the configuration options: default_groups must be a list of group names/ids (i.e. strings)
I've done my best to be thorough here but please feel free to ask me any additional questions for clarification. I'd be very grateful for any insight/help with figuring this out.
Lastly, I have a couple of hunches that I'm still exploring. One is that there might be a version compatibility issue with the more recent version of CKAN (2.5) and the current Harvester version. I suspect this because the other versions of CKAN where the Harvester is actually working are running 2.2.
Not sure if that will mean anything to someone more familiar with the platform.
I'm open to all ideas, solutions, hunches, or whatever else might help me resolve this!
