Form will not render from Workspace

I have an xfaForm that will be filled out to kick off a workflow via a TaskManager endpoint. However, when I try to start the workflow from within Workspace, it throws the following error code at me:

ALC-WKS-007-040

I have triple checked that my form and workflow meet the following criteria:

1) The variable I am using for my form is of type xfaForm
2) The variable I am using for my form is set to both "Input" and "Required"
3) The render service for the form is set to "Default Render" (invoke)
4) A button exists on the form and is set to "Submit"

I was under the impression that should the above for criteria be met, that a form should render but am I missing something?

Thanks in advance!
