I am trying to add a New Site Module to the Website, and it is working fine for the first time. But when I try to create a second Module and try to add it, it is giving me error. Please see below the steps, and let me know if what I am doing wrong.

For 1st Site Module, say Top Navigation

  • I added a Site Module in system\settings\Feature\Tenant. I selected Site Module Option in the Wizard. It runs fine.
  • I Cloned a Rendering say Page Content and added that to the Top Navigation Module. For Rendering Parameters & Datasource, I created a copy, and View I used the Original one. It also gets created fine.
  • I went to the Site Node, and from Scripts, I selected Add Site Module Option. In the Wizard, the new Module is coming up, and installed that. For this time, it also gets installed fine.

Now, I created a second Site Module say Left Navigation. I followed the above steps for this one as well.

  • I added a Site Module in system\settings\Feature\Tenant. I selected Site Module Option in the Wizard. It runs fine.
  • I Cloned a Rendering say Page Content and added that to the Left Navigation Module. For Rendering Parameters & Datasource, I created a copy, and View I used the Original one. It also gets created fine.
  • I went to the Site Node, and from Scripts, I selected Add Site Module Option. In the Wizard, the new Module is coming up, and installed that. However this time, it is giving error.

Please see the error below.

I am using Sitecore 9.3 with SXA 9.3. Any leads will be very helpful.

I checked further, and found out that the above works fine on a Single Site Setup. It is giving issue when I have two sites in a Tenant.

For this issue, I connected with Sitecore Support, and they have admitted it as a bug. Please see below their response.

Thank you for contacting Sitecore Support!

During the investigation, I was able to reproduce the issue in my local environment. The behavior you reported was registered as a bug in our bug tracking system. Thank you for reporting the problem.

To track the future status of this bug report, please use reference number 432170. More information about public reference numbers can be found here: https://kb.sitecore.net/articles/853187.

As a workaround for the issue, please try performing the following steps:

Navigate to '/sitecore/system/Modules/PowerShell/Script Library/SXA/SXA - Scaffolding/Functions/Scaffolding/Rendering/Copy-Rendering' item;
Insert the following lines to script:
...
$availableRenderingsAction."Location" = "{84179507-91A2-47EA-A424-9D338F64C953}"
$availableRenderingsAction.Editing.BeginEdit();
$availableRenderingsAction."__Name" = $model.TargetModule."Name";
$availableRenderingsAction.Editing.EndEdit();
$TemplatesFolderForFeature = Get-BranchesFolderForFeature $model.TargetModule
...

These lines will assign 'Name' field value of 'Add Available Renderings' item during Rendering Cloning.
Alternatively, you could set 'AllowDuplicateItemNamesOnSameLevel' setting to "true" in Sitecore.config file.
