Description

The Sitecore Command Line Interface (CLI) serialization commands might fail if different "includes" nodes reference to nested paths in a module's configuration file. 

For example, when executing the command:

dotnet sitecore ser pull 

An error similar to the following can appear in the console (note that it might be necessary to run the command 2 times to get it):

Detected the item with ID a2b9c39c-9a19-4067-910a-90c84f93ae9d existed on disk in more than one place (C:\inetpub\wwwroot\sc10.2sc.dev.local\src\serialization\master\sitecore\content\test\TEST.yml + more). Use the validate command to diagnose the problem.

The issue affects CLI starting from 3.0.0 version.

Solution

As a solution, consider avoiding nested names in "includes".

 For example, instead of:

{ 
    "namespace": "test",
    "items": {
        "includes": [
            {
                "name": "A/B/C",
                ...
            },
            {
                "name": "A/B/C/D", // <---- will not work correctly
                ...
            }
        ]
    }
}

use:

{ 
    "namespace": "test",
    "items": {
        "includes": [
            {
                "name": "A/B/C",
                ...
            },
            {
                "name": "X/Y/Z/D",  // <---- will work correctly
                ...
            }
        ]
    }
}
