result with empty issue list

[ep-mo]

When exporting from ActiveCollab the issue list sometimes return empty. I'm exporting from AC cloud (PR #1) and have not tested if the issue is relevant to SelfHosted AC as well.

Not sure why, but when I removed this line of code locally, the script seems to be working as expected again:
