Tried to "Parse JSON" but dosen't get results.

[Sam44]

I'm building Canvas app and my data source is SharePoint list.

In my SharePoint list, I have column named "CartItems" and I would like to store collection data as JSON format.

With button, I wrote:

Patch('Datasource',{ID:ID},
{Title:MyItems,
 MyFavoriteItems:JSON(colMyFavoriteItems,JSONFormat.IndentFour)
}
)

As a result , I have below data in column named "CartItems".

[
    {
        "ID": 8,
        "ItemCategory": "DRINK",
        "ItemLinkURL": "https://hogehoge.com",
        "ItemPictureURL": "https://picturexxxxxxxxxxxx.jpg",
        "ItemCode": "4987035332602",
        "MinimumOrderUnit": 1,
        "RegularPrice": 3108,
        "ShowHide": true,
        "Title": "Coke 500ml"
    }
]

Then I placed one more button to parse this JSON into collection to show them to the gallery.

ClearCollect(colMyFavoriteItems, 
             MatchAll(CartItems,"(""ID"":(?<ID>[^""]*),""ItemCategory"":""(?<ItemCategory>[^""]*)"",""ItemLinkURL"":""(?<ItemLinkURL>[^""]*)"",""ItemPictureURL"":""(?<ItemPictureURL>[^""]*)"",""ItemCode"":""(?<ItemCode>[^""]*)"",""MinimumOrderUnit"":""(?<MinimumOrderUnit>[^""]*)"",""RegularPrice"":(?<RegularPrice>[^""]*))"))

but doesn't have any results....

I'm learning this with this great video  https://www.youtube.com/watch?v=M2033jUWqRY&t=1170s

Could someone know what is missing with my code.

Thanks.
