How to input in a multiselect field on a Kommo module?

Hello.

I’m very new to Make and currently I’m having trouble to input values into a custom multiselect field on a Kommo module (“Create a Lead”).

The values come from a Google Sheets sheet, and I already made it work to normal custom fields through the option “Custom Fields as an Array” and using this input format:

{"value":"{{ref_to_field}}"}

But, when I try doing the same to this multiselect field (it’s a category field), it just works when there’s just one category. If there’s more than one (comma-separated values), the module returns me a RuntimeError: [400] Bad Request Request validation failed.

I know that’s because the value are arriving as just one value, like “X, Y” when they should be two different values “X” and “Y”, but I don’t know how to properly input it in the module.

The input from the module (the only real value I left unanonymized was the one in the field in question):

[
    {
        "name": "XXXXXXXX",
        "_embedded": {
            "tags": [
                {
                    "id": 99999
                }
            ]
        },
        "status_id": 8629999,
        "cfSelector": "array",
        "created_at": "2025-01-01T12:00:00.000Z",
        "created_by": 99999999,
        "contacts_id": [
            99999999
        ],
        "pipeline_id": 99999999,
        "custom_fields_values": [
            {
                "values": [
                    "{\"value\":\"Entretenimento, Arte e Criatividade\"}"
                ],
                "field_id": 999999
            }
        ]
    }
]

The correct values that the field can receive:

I hope I made myself clear and gave the proper informations. I’m open for suggestions of how I can solve this issue.
Thank you and have a good day.
