Assign more than 1 category to woocommerce product ("update product" module)

my main goal is to only ADD one category (Category id: 207) to the product, without changing it current categories.

im trying to assign more than one category in woocommerce “update product” module.
i toggle on the “map” option and tried to assign the categories by their number.
when i enter only one number (one category) – it works fine. but if i try to assign 2 categories or more i get an error…

what could be the problem and how can i achieve my goal?
Thanks

Welcome to the Make community!

When you are using the “Map” toggle, the field expects the same data structure as originally provided, and it might not just be a simple comma-delimited string - it could be an array or collection.

Can you take a screenshot of how the Categories of the product data bundle (Output) looks like in a previous module?

Or can you export that Output bundle and paste it above so we can see how it is structured?

hey samliew, i tried both array and collection, none worked, here is what i tried:
[21, 19] and {
“id”: 21,
“id”: 19
}
here is the output of the working bundle with two category selected:
“categories”: [
{
“id”: 20,
“name”: “test”,
“slug”: “buy-test”
},
{
“id”: 19,
“name”: “red”,
“slug”: “sell-red”
}
],
