Public bug reported:

In Jenkins-2.32.3, when running get_running_builds(), if an executor has
no executeables, it removes the array and replaces it with a string
"None", resulting in errors.

            for executor in info['executors']:
                executable = executor['currentExecutable']
                if executable and 'PlaceholderTask' not in executable.get('_class', ''):
                    executor_number = executor['number']
                    build_number = executable['number']
                    url = executable['url']
                    m = re.search(r'/job/([^/]+)/.*', urlparse(url).path)
                    job_name = m.group(1)
                    builds.append({'name': job_name,
                                   'number': build_number,
                                   'url': url,
                                   'node': node_name,
                                   'executor': executor_number})
        return builds


>>> info_master = server.get_node_info('(master)', depth=2)

As seen below, the currentExecutable key in the second executor (number:
1) is not an array, but rather a string "None", causing the build.append
to fail and return an error.

>>> info_master['executors']
[{u'likelyStuck': False, u'number': 0, u'idle': False, u'currentWorkUnit': {}, u'progress': 92, u'currentExecutable': {u'_class': u'org.jenkinsci.plugins.workflow.support.steps.ExecutorStepExecution$PlaceholderTask$PlaceholderExecutable'}}, {u'likelyStuck': False, u'number': 1, u'idle': True, u'currentWorkUnit': None, u'progress': -1, u'currentExecutable': None}
