Can't view jobs in Ruby qless-web: bad argument #1 to 'decode' (string expected, got boolean)

[drauschenbach]

Set a breakpoint on any unit test that creates a job. Run the qless-web Ruby console, find the queue, then navigate to the waiting or other job state filter via one of the nav tabs. The web client won't be able to display the job.

sinatra.error:
