Not able to get the result in the German language, when executing the Catalog API Search call for DE marketplace.

Summary

I am executing the Catalog API Search call for DE marketplace and not getting the response/result in the German language. 

Detailed Description

There can be several reasons for this issue. One of the reasons can be using the multiple values for x-ebay-c-marketplace-id request header. Check for the x-ebay-c-marketplace-id request header and use only one value EBAY_DE for the header. (do not use multiple values for the request header)

cURL Code snippet for the call below:

curl --location 'https://api.ebay.com/commerce/catalog/v1_beta/product_summary/search?q=Telefon&category_ids=-1&fieldgroups=FULL' \
--header 'Authorization: Bearer v^1.1#i^1#r^0#I^3#f^0#p^3#tfb' \
--header 'Accept: application/json' \
--header 'Accept-Encoding: gzip' \
--header 'X-EBAY-C-MARKETPLACE-ID: EBAY_DE'\
