Could please anyone explain me why I´m getting this error when I´m trying to remove the last item of an array.

Here the array.

this.customsTypes = [
    {
        "id": "D1",
        "title": "d1",
        "icon": "",
        "hasDeleteIcon": true,
        "deleteIcon": "<img src=\"assets/icons/trash_icon.svg\">"
    },
    {
        "id": "D2",
        "title": "d2",
        "icon": "",
        "hasDeleteIcon": true,
        "deleteIcon": "<img src=\"assets/icons/trash_icon.svg\">"
    },
    {
        "id": "DISTRIBUCIÓN__18/07/2023",
        "title": "Distribución  18/07/2023",
        "icon": "",
        "hasDeleteIcon": true,
        "deleteIcon": "<img src=\"assets/icons/trash_icon.svg\">"
    }
]

Here the use of splice:

const idIndex = this.customsTypes!.findIndex((e) => e.id === id);
this.customsTypes!.splice(idIndex, 1);

Here the error I get on console:

Uncaught TypeError: Cannot delete property '2' of [object Array] at Array.splice ()

  • Can you post how are you using this code. What is your id variable here Commented Jul 18, 2023 at 11:05
  • id value is the value of the property id. For example "D2" Commented Jul 18, 2023 at 15:03
