Create product with multiple lines metafields in shopify

Help me Build my Workflow
1

I can’t seem to find a way to split the input of the values in to two values when using the api to put some data in the metafield tall custom.tilleggsprodukter when creating a product in Shopify. It is always just the last line which get inserted. Its like multi lines doesnt work while using api.
Anyone managed to get this working?
Here is the two suggeestion I have tried, and experimented with \n \r\n etc. but always just the last line which gets implemented. Yes, the type is correct for the metafield.

{
“product”: {
“title”: “Example Product with Metafield18”,
“body_html”: “Good product!”,
“vendor”: “Example Vendor”,
“product_type”: “Example Type”,
“variants”: [
{
“option1”: “Default Title”,
“price”: “19.99”,
“sku”: “123”,
“inventory_management”: “shopify”,
“inventory_quantity”: 100
}
],
“metafields”: [
{
“namespace”: “custom”,
“key”: “tilleggsprodukter”,
“value”: “["value_1", "value_2"]”,
“type”: “list.single_line_text_field”
}
]
}
}

Hey, when placing " inside " " (like “[“value_1”, “value_2”]”) you need \ before the inner " (like: “value”: “[\“value_1\”, \“value_2\”]”) for your value to be considered proper json.

An example of n8n detecting it like an incorrect json :

Tell me if this fixes the problem, if not we would need to look in Shopify documentation. Also, what error does Shopify throw ?

Edit : it doesn’t show \" unless you double \ here, I guess you put the correct format as you said, sorry for not noticing.
