While upgrading from PHP 7.x to 8.x, CatalogItemsV20220401Api->searchCatalogItemsRequest() throws the following exceptions:

Based on the error, it looks like you're passing a single marketplace ID instead of an array of marketplace IDs.

Hi jlevers, appreciate the swift response.

I am passing "A comma-delimited list of Amazon marketplace identifiers for the request" - I'm quoting the comment from the documentation [1] and not an array.

Even if using an array, the exact same exception is thrown.

After looking at the code, indeed there is nothing wrong with it.

It's just the instructions in the comments next to the arguments that are misleading: "string[] | A comma-delimited list of Amazon marketplace identifiers ..." "A comma-delimited list of product identifiers ..."

There is no "comma-delimited list", these are all arrays.

Thanks for your time.

Got caught by this too. For anyone else -- both $identifiers and $marketplace_ids args expect arrays and not comma-delimited strings (and other arguments saying "comma-delimited list" for that matter).

Main gotcha comes from the fact that I already used getCatalogItem by sending it a single marketplace id string and it worked without issues, so I assumed that is the correct usage, but it actually only works by accident.
