MetaClass error REST service

Support
#1

Hi,
I have developed a REST service to return a list of strings and it is giving me this error:

  
ERROR c.h.r.s.ServicesControllerManager - MetaClass for service collection parameter type class java.lang.String not found

Service in FechasInventariosService.java

 List<String> fechasInventarios(String tienda, String tipo);

Service in rest-services.xml

  <service name="inventarios_FechasInventariosService">
        <method name="fechasInventarios">
            <param type="java.lang.String" name="tienda"/>
            <param type="java.lang.String" name="tipo"/>
        </method>
   </service>

What is wrong?

Thanks in advance!

Hi,
this is a bug. It occurs when your method returns an empty list. The issue: https://youtrack.cuba-platform.com/issue/PL-10263
