There must have been a change made to the api recently, because the call to get all of the workers is no longer returning the worker id for each of the workers. Instead, I am just getting:
[{ browser: 'firefox',
version: '15.0',
os: 'win',
status: 'running' },
{ browser: 'firefox',
version: '15.0',
os: 'win',
status: 'queue' }]
What happened to the worker ids? They were in that array last week...
