Error returning a skill I created that grants permission from another plugin

I've created a new skill that gives you permission to put a codelock on horses; the code I added is this:

{
          "Enabled": true,
          "Skill ID": 59,
          "Skill Type": "PermissionGrant",
          "Title": "Bloqueo Caballos",
          "Description": "Posibilidad de bloquear tu caballo mediante un codelock, recuerda estar en permisos de armario y los componentes o un codelock para poder crear el bloqueo",
          "Image": "https://gitlab.com/TheMevent/PluginsStorage/raw/main/Images/Skills/Icons/Teleportation.png",
          "Permission": "",
          "Requirements to access skill": [],
          "Permission Grant Settings": {
            "Levels (each level grants its permission)": [
              {
                "Permission To Grant Player": "vehicledeployedlocks.codelock.ridablehorse",
                "Group To Grant Player": "",
                "Value": 0.0,
                "Cost": 300.0,
                "Permission": "",
                "Requirements to access level": []
              }
            ]
          }
        }

The permission is granted correctly, but when you try to remove that skill, it gives this error in the console and the plugin stops working.

Can you tell me how to fix it?

We will release an update soon that will include a fix for this as well

Granting permission works fine, but it fails when removing any permission by returning the skill.
