Problem with a job (scheduler caught exception)

Author: LKLGCreated Nov 5, 2013Updated Jan 16, 2018

I have a job to get data from a mysql-Database in the Rickshawgraph widget (https://gist.github.com/jwalton/6614023). However, the job does not run. Log:

scheduler caught exception:

So i've looked at the script, but i doesn't find the problem. "(0..7).each do |i|" is line 112

ruby

series = [
  {
    name:"Erstellte Tickets",
    data: []
  },
  {
    name:"Geschlossene Tickets",
    data: []
  }
]
z = 0

(0..7).each do |i|
  z = i - 1
  series[0][:data][z] = {x:prevdays(i,0,1), y:get(1)[0][i]}
  series[1][:data][z] = {x:prevdays(i,0,1), y:get(1)[0][i]}
end

So i tested the code with irb and there is no error or problem and everything is as it should. So my question. Where is the Problem?

And sorry for my english..
