Problem with Letsfreckle::Entry.find

[ThomasG17]

Hello,

I have a problem with the search entries.
I put "LetsFreckle::Entry.find" in my controller, it returns me a 400 error,while I put the URL directly into a browser a result is displayed.

LetsFreckle::Entry.find(:from => '2014-07-10').each do |entry|
puts entry.description
end

Fetch failed, HTTP error: 400
