Symptoms
Please help to resolve error accessing K2 WF with InfoPath Form.
Diagnoses
The workflow was needed to be configured on a new SharePoint 2013 site in 2010 mode. The workflow needed to be deployed along with the creation of the library.
Resolution
There were some access errors caused by the SharePoint configuration. Once they were cleared out we were able to work with the site. Re running the InfoPath Integration Wizard from the workflow, pointing to the new site, creating a new Forms Library and deploying the workflow resolved the issue.
