I've checked the latest deeplink module from the appstore based on your error/stacktrace. The row numbers don't match, but I have a guess on which row it fails when a deeplink has been called. What I discoverd in the javasource incombination is with a Java library what should be delivered by the Mendix environment. The Java library isn't added in the module from the appstore.
What you can do is search in de Mendix Modeler installation to javax.servlet.api.jar and add this library in the userlib folder.
