Endpoint 'productPricing', operation 'getCompetitivePricing' does not work correctly with Asins

[altruer-old]

When you add query parameters

ItemType: 'Asin',
Asins: ['B00WII52ZU', 'B08T68JQNP'],

You get

[
{
"ASIN": "B00WII52ZU, B08T68JQNP",
"status": "ClientError"
}
]

Problem is that lib does twice encoding (what is got from /amazon-sp-api/lib/resources/versions/product_pricing/productPricing_v0.js)

Single encoding is enough here
So I propose to remove encode_twice:true for this endpoint

Please check how it will behave with SKU array

Thanks!

We get the same problem when submitting an array of Asins. Setting encode_twice:false fixes for us. As per OP unsure whether special characters in SKU might cause a problem with encode_twice:false?

Hi @altruer, @colin-brown,

we fixed the issue. The reason was actually that because of the necessary double encoding for skus with special chars for the two operations getPricing and getCompetitivePricing, the array delimiter , was also encoded twice, resulting in Amazon not being able to split up the array. Thats why the two ASINs were not received as two separate array values but as one: "ASIN": "B00WII52ZU, B08T68JQNP".

What still persists now is the issue of Amazon splitting up an array value containing a , into two values when part of the query. There's no real fix for it yet, but the issue is already communicated to Amazon.

Thank you very much, works as expected now!
