Hi Creatio Community,

I am working on extending the existing implementation of the Execute method in the web service designer, which is part of a base package in Creatio. My goal is to modify the method to add additional functionality: specifically, I want to save the web service response as a record using an EntitySchemaQuery (ESQ), so that the response can be displayed in a custom section inside Creatio.

However, I am encountering a compilation error:

Error:
cannot convert from 'System.Collections.Generic.IEnumerable<Terrasoft.Configuration.ServiceSchemaParameter>' to 'System.Collections.Generic.IEnumerable<Terrasoft.Configuration.ServiceSchema.ServiceSchemaParameter>'

It appears that the system is having difficulty converting between two types that have the same name but are possibly from different namespaces. I am using ServiceSchemaParameter in my custom implementation, but the IServiceSchemaClient.Execute() method is expecting the parameter to be of a slightly different type.

Here’s an overview of my approach:

1. I've modified the Execute method to include an ESQ that logs the web service call and stores the response.
2. The issue arises when passing the parameters (of type List<ServiceSchemaParameter>) to the Execute method, where it's expecting IEnumerable<ServiceSchema.ServiceSchemaParameter>.
3. I believe the conflict is due to namespace ambiguity or mismatched types between base and custom implementations.
   
   My code:

   {
    
    
       using System;
       using System.Linq;

Request:
Could anyone guide me on how to properly resolve this type conversion issue? If there is a better way to manage the namespace or cast the types correctly, I would appreciate any advice or best practices to ensure compatibility between the types.

Thank you for your help!
