In Acumatica version 2024 R2 we are creating a communication with an API that we send a List<string> and they return a List to us<object>, but when sending, it tells us this error
<?xml version="1.0" encoding="UTF-16"?><s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"><s:Body><s:Fault><faultcode xmlns:a="http://schemas.microsoft.com/ws/2005/05/addressing/none">a:ActionNotSupported</faultcode><faultstring xml:lang="es-EC">The message with Action 'http://tempuri.org/IService/ProcesarXmlRecepcion' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).</faultstring></s:Fault></s:Body></s:Envelope>
It should be clarified that other methods that we have programmed in version 2023r2, do work for us
