[sumo-user] Warning: unable to open primary document entity 'xsd/routes_

[Jose Monreal Bailey <jmonreal@xxxxxxxxx>]

Hey everyone,

I am getting the following warning,

Warning: unable to open primary document entity 'xsd/routes_file.xsd'
 In file '/home/user/4/scenario.rou.xml'
 At line/column 1/0.

My rou.xml file has the relative path to the xsd just like all other xml files from the simulation and this is the only one that gives that warning, is there anything that it can be done?

<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="xsd/routes_file.xsd">

Best regards,

Jose
