PUT /listings/2021-08-01/items/{sellerId}/{sku} returns 403 when SKU is empty.

Using https://github.com/go-swagger/go-swagger generated client with the models provided from this repository.

When the Sku parameter for https://developer-docs.amazon.com/sp-api/docs/listings-items-api-v2021-08-01-reference#put-listings2021-08-01itemsselleridsku is empty, API returns

1:02AM FTL error="[PUT /listings/2021-08-01/items/{sellerId}/{sku}][403] putListingsItemForbidden {\"errors\":[{\"code\":\"Unauthorized\",\"message\":\"Access to requested resource is denied.\"}]}"

and when I put random gibberish, like params.Sku = "W9-EYD8-3O", it is back to normal.

1:02AM FTL error="[PUT /listings/2021-08-01/items/{sellerId}/{sku}][400] putListingsItemBadRequest {\"errors\":[{\"code\":\"InvalidInput\",\"message\":\"The provided payload is invalid.\"}]}"

Literally nothing changed between this two requests, I only supplied a SKU value.

I dont even know where to report this, I know this is just a models repository, but, currently, this is very misleading and confusing behavior.

Hi @caner-cetin

SKU is a required path parameter for putListingItem operation. Empty SKU value could cause issues in the API call.

I understand it required, but throwing Access denied with 403 status code is the main issue i was pointing at.
