Mule ESB: unable to copy message with thread payload

I have a Mule application in which I send a request to several web services and aggregate the list of answers that I receive, the idea is to get the first answer of the list by returning it from CustomJavaClass, where the list is processed:

return responses.get(0);

I can achieve WSDL if I try to contact it through a browser, the returned WSDL looks as if it should look. But I'm trying to send a message through SoapUi, I get the following exception:

 Exception stack is: 1. Cannot copy message with a stream payload. Payload type is "org.apache.commons.httpclient.ContentLengthInputStream". Message payload is of type: ContentLengthInputStream (org.mule.api.MessagingException) org.mule.routing.outbound.AbstractSequenceRouter:73 (http://www.mulesoft.org/docs/site/current3/apidocs/org/mule/api/MessagingException.html) -------------------------------------------------------------------------------- Root Exception stack trace: org.mule.api.MessagingException: Cannot copy message with a stream payload.

SOAPUi exception:

my current configurations are:

Getting WSDL works because the GET request does not carry any payload. But when you try to call the SOAP method, the POST payload is an InputStream, which, of course, cannot be sent multiple times.

Thus: serialize the HTTP input stream with:

 <object-to-byte-array-transformer />

immediately after http: inbound-endpoint.
