Trouble setting Output Module Settings for Format

Hello! Based on the Documentation, I should be able to set the settings on the Output Module by doing:

render_queue = engine.adobe.app.project.renderQueue
render_item = render_queue.item(1)
output_module = render_item.outputModule(1)
output_module_data = {
"Format": "QuickTime",
}
output_module.setSettings(output_module_data)
print(output_module.getSettings().toSource())

 However, when I try to set settings in this way, there is no effect. I saw there's a bug that causes "[the] OutputModule object to be invalidated after the output module setting is modified, so you need to retrieve the Output Module again after you modify it." I tried reselecting, but either way the setting does not seem to be modified. Can anyone help?
