How to log web services and record them in a section

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: 
     
  4. namespace Terrasoft.Configuration
    {
     
     
        using System;
        using System.Linq;
        using System.Collections.Generic;
        using System.Runtime.Serialization;
        using System.ServiceModel;
        using System.ServiceModel.Web;

        using Terrasoft.Core.Factories;
        using Terrasoft.Services;
        using Terrasoft.Web.Common;
        using Terrasoft.Core;
        using Terrasoft.Core.Entities;
        using Terrasoft.Configuration.ServiceSchema;

    		public CallServiceSchemaResponse Execute(string serviceName, string methodName, List<ServiceSchemaParameter> parameters) {
    			if (parameters == null) {
    				parameters = new List<ServiceSchemaParameter>();
    			}
    			try {
    				UserConnection.DBSecurityEngine.CheckCanExecuteOperation("CanManageSolution");
     
    				// Getting the builder and client from the ClassFactory
    				var builder = ClassFactory.Get<IServiceSchemaParameterBuilder>();
    				var serviceSchemaClient = ClassFactory.Get<IServiceSchemaClient>();
     
    				// No need to cast, List<T> already implements IEnumerable<T>
    				var serviceResponse = serviceSchemaClient.Execute(UserConnection, serviceName, methodName, builder.Build(parameters.AsEnumerable()));
     
    				// Log the request and response
    				LogWebServiceCall(serviceName, methodName, parameters, serviceResponse);

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!

Looking forward to your suggestions and insights!

Hello Pranshu Basak,

Please change the part of the code 

var serviceResponse = serviceSchemaClient.Execute(UserConnection, serviceName, methodName, builder.Build(parameters.AsEnumerable()));

to the new one:

var serviceResponse = serviceSchemaClient.Execute(UserConnection, serviceName, methodName, builder.Build((IEnumerable&lt;ServiceSchema.ServiceSchemaParameter&gt;)parameters.AsEnumerable()));

for solving the compilation error.
