Error in module (veins::obstaclecontrol)

Question

I defined a simple map in sumo with 5 edges and inserted it in my veins but I get this error

error in module (veins::obstaclecontrol) rsuexamplesenario.obstacles (id=2) at event #467, t=46:unable to use simpleObstacleShadowing: no obstacles have been added.

I don't know how to remove obstacles from config.xml and omnetpp.ini file in veins.

Comment out these lines in the ini file:

*.obstacles.debug = false
*.obstacles.obstacles = xmldoc("config.xml", "//AnalogueModel[@type='SimpleObstacleShadowing']/obstacles"‌​)

Comment out these lines in the config file:

<AnalogueModel type="SimpleObstacleShadowing">
   <parameter name="carrierFrequency" type="double" value="5.890e+9"/>
   <obstacles>
      <type id="building" db-per-cut="9" db-per-meter="0.4" />
   </obstacles>
</AnalogueModel>
