Inconsistent BIRT dashboard widget deployment?

 I'm trying to deploy a custom Micro BIRT report. I've done this in the past and have hit no issues. However, the report that I'm currently trying to  deploy as a dashboard widget returns "no results found". If I click on the actual report title and go to the URL of the report itself - I'm met with a giant error message. I've made sure that the output of the BIRT chart has been set to .PNG. Any thought on what to do here?
