question

This error is because your network node path isn't set up correctly. Any time a patient travels to an object you need to make sure you have an "A" connection from one of the network nodes to that object, so that the patient or staff resource can travel there. Doing that fixed the first error message, but it looks like you have more than one instance of this in your model. For a review on setting up these paths there are a few sections in the user manual under the "Patient and Staff Movement" section.
