• The targetModelId assignment uses the null-coalescing operator with template.Id as fallback, but there's no validation that targetModel is not null after the repository call. If GetByIdWithChildrenAsync returns null, this will cause a NullReferenceException when the model is accessed later. Add null check after line 99.

• Missing null check after loading project from repository. If the project with template.ProjectId doesn't exist, the GetByIdAsync call could return null, causing a NullReferenceException when accessing project.RootPath on line 55. Add a null check and appropriate error handling.
