How to set "key marketplaceIds: array"?

[ShakMitz]

HI.

Marketplaces.US.marketplace_id
CatalogItems
def get_catalog_item (self, asin, ** kwargs)

There are "asin" and "kwargs" parameters in the arguments.

Args:

asin: string | * REQUIRED The Amazon Standard Identification Number (ASIN) of the item.

key marketplaceIds: array | * REQUIRED A comma-delimited list of Amazon marketplace identifiers. Data sets in the response contain data only for the specified marketplaces.

:
:

Set the list in "marketplaceIds: array" in dictionary format in "kwargs".

`
**Instance is generated in US

catalogItems_obj = CatalogItems (
marketplace = Marketplaces.US,
credentials = credentials,
)
**Credentials ('refresh_token') >>> US refresh_token

List because I want to get #US and CA
MarketplaceParamList = [
Marketplaces.US.marketplace_id
Marketplaces.CA.marketplace_id,
}
**Add to dictionary
prmDict = dict (
marketplaceIds = MarketplaceParamList,
)

**Call API
res = catalogItems_obj.get_catalog_item (
asin =''B0xxxxxx',
kwargs = prmDict
)
`

result

CA cannot be obtained (US only)

I want to get both US and CA, but I can only get US.

What should I do with this?
