Cannot bind source content type Umbraco.Cms.Web.Common.PublishedModels.FrontPage to model type MyProject.Models.Generated.FrontPage

[truongtphat]

Hi, I'm using Umbraco to develop a website. So I have issue after deploying the site on IIS.
I'm using Model Builder and configuration it as below:

"Umbraco": {
    "CMS": {
      "Global": {
        "Id": "b76bb887-7913-4bb4-9431-7d75f7b56db0",
        "SanitizeTinyMce": true
      },
      "Content": {
        "AllowEditInvariantFromNonDefault": true,
        "ContentVersionCleanupPolicy": {
          "EnableCleanup": true
        },
        "ModelsBuilder": {
          "ModelsMode": "SourceCodeManual",
          "ModelsNameSpace": "MyProject.Models.Generated",
          "FlagOutOfDateModels": true,
          "ModelsDirectory": "~/Models/Generated",
          "AcceptUnsafeModelsDirectory": false,
          "DebugLevel": 0
        }
      }
    }
  }

After publishing the project then I copied all file in publish folder into IIS website folder.
I got issue after running the site
