AuthorizerConfigurationException from getOrders (Vendor Direct Fulfillment Orders API)

[virtutemdave]

I'm calling the Vendor Direct Fulfillment Orders API getOrders endpoint (/vendor/directFulfillment/orders/v1/purchaseOrders). This requires a Restricted Data Token (RDT). I am able to get the RDT, but when I call getOrders I get an AuthorizerConfigurationException. When I was debugging, I noticed that the URL created added multiple marketplaceId parameters. They all had the same value, ATVPDKIKX0DER for the US. Do you think that would cause this issue?

This is the generated URL:

/vendor/directFulfillment/orders/v1/purchaseOrders?createdAfter=2022-04-14T02%3A00%3A00Z&createdBefore=2022-04-14T02%3A59%3A59Z&MarketplaceId=ATVPDKIKX0DER&MarketplaceIds=ATVPDKIKX0DER&marketplace_ids=ATVPDKIKX0DER&marketplaceIds=ATVPDKIKX0DER

TIA,
David

I don't think that's causing the issue, it works fine for all other endpoints and is intended (accounts for all possible parameter name-styles/casing, Amazon ignores the others).

Can you share how you're creating the rdt? Any errors there?
