Hello,
The error indicates that the pedestrian did not find a place to cross the
street.
Take a look at this guide:
http://sumo.dlr.de/wiki/Simulation/Pedestrians#Building_a_network_for_pedestrian_simulation
You need to either guess the crossings or define them manually.

regards,
Jakob

>     <node id="b140338939" type="unregulated" x="...." y="..."/>
>     ....
> </nodes>
