Can't call a customer web service that uses anonymous authentication from the browser using this link :  "http://mycreatio.com/0/ServiceModel/UsrCustomConfigurationService.svc/GetContactIdByName?Name=User1"

Hello Community,

When calling a custom web service that uses anonymous authentication from the browser using this link : 

"http://mycreatio.com/0/ServiceModel/UsrCustomConfigurationService.svc/G…"

The page does not seem to work.

Note :  we have an on premise Creatio instance on Linux based on .Net Core.

Bellow are the steps to reproduce the case:

The Academy guides on how to Create a custom web service that uses anonymous authentication for .NET Core : https://academy.creatio.com/docs/developer/back_end_development/web_ser…

This is the class indicated in the first step (that returns the contact ID by the contact name) : 

namespace Terrasoft.Configuration.KycCustomConfigurationService {

    using System;

    using System.ServiceModel;

    using System.ServiceModel.Web;

    using System.ServiceModel.Activation;

    using Terrasoft.Core;

    using Terrasoft.Web.Common;

    using Terrasoft.Core.Entities;

    using Terrasoft.Web.Http.Abstractions;

    [ServiceContract]

    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]

    public class KycCustomConfigurationService: BaseService {

        private SystemUserConnection _systemUserConnection;

        private SystemUserConnection SystemUserConnection {

            get {

                return _systemUserConnection ?? (_systemUserConnection = (SystemUserConnection) AppConnection.SystemUserConnection);

            }

        }

        /* The method that returns the contact ID by the contact name. */

        [OperationContract]

        [WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped,

            ResponseFormat = WebMessageFormat.Json)]

        public string GetContactIdByName(string Name) {

            SessionHelper.SpecifyWebOperationIdentity(HttpContextAccessor.GetInstance(), SystemUserConnection.CurrentUser);

            var result = "";

            var esq = new EntitySchemaQuery(SystemUserConnection.EntitySchemaManager, "Contact");

            var colId = esq.AddColumn("Id");

            var colName = esq.AddColumn("Name");

            var esqFilter = esq.CreateFilterWithParameters(FilterComparisonType.Equal, "Name", Name);

            esq.Filters.Add(esqFilter);

            var entities = esq.GetEntityCollection(SystemUserConnection);

            if (entities.Count > 0) {

                result = entities[0].GetColumnValue(colId.Name).ToString();

                result = entities[0].GetTypedColumnValue(colId.Name); */

            }

            return result;

        }

    }

}

and this is the changes to the ..\Terrasoft.WebHost\appsettings.json file

"Terrasoft.Configuration.KycCustomConfigurationService": [

                                "/ServiceModel/KycCustomConfigurationService.svc"

                        ]

Thank you,
