MuleSoft REST API invoking SOAP Service - rest

Question

I invoke a SOAP Service that calls data from a DB using a REST Service, when I call the GET function it returns all null values and the Anypoint Studio Console returns this answer:
INFO 2020-11-19 08:51:40,897 [[MuleRuntime].uber.03: [userstory12_soap].getCustomerByLastName.BLOCKING #393df87f] [processor: ; event: bb2e3fd0-2a76-11eb-9a6c-86c5a63076bd] org.apache.cxf.wsdl.service.factory.ReflectionServiceFactoryBean: Creating Service {http://client.internal.soap.mule.org/}ProxyService from class org.mule.soap.internal.client.CxfClientFactory$ProxyService
I do not know why is it not working, since I compared my flows with those of a colleague and they are exactly the same (except for some minor variations in variable names). Any input in solving this would be great! Find below screenshot of my flows and XML
