daily_active method fails

[fcojavierdomenech]

my code, change to a real app id and use valid credentials, the rest of methods are working just fine

spec = Gem::Specification.find_by_path('fabricio')
spec.activate
gem_original_require 'fabricio'

client = Fabricio::Client.new do |config|
    config.username = 'javi@*********.com'
    config.password = '*********'
end

date_ini = Time.new(2017,12,01)
date_end = Time.new(2018,01,01)

builds = [
    "1.7.6 (114)"
]

app_id =  '5677c7ae1b5c0932*******'

result = client.app.send("daily_active", *[app_id, date_ini.to_i, date_end.to_i, builds]);
print result
exit

Output:
