500 Internal Server Error : Required key 'asin' does not exist in Audible API response

[MaxPowers1337]

Hi all,

i'm currently having the issue that the audnex api says seems not to find a book by ASIN althoug its available.

{
  "statusCode": 500,
  "error": "Internal Server Error",
  "message": "Required key 'asin' does not exist in Audible API response for ASIN B0DFHJFZQH"
}

Shouldnt it return code 404 when not finding a match according to the documentation? Seems to me that the Audible API response is missing the ASIN attribute completly?

Working example is
https://api.audnex.us/books/B0D8W2332M?region=de

The same happens when calling https://api.audnex.us/books/B0DFHJFZQH?region=de, but the book is available on Audible.
