BC PIM Connector - Duplicate JSON key error when publishing pending products

Description

We are testing the BC PIM Connector for an Advania webshop implementation and encounter a failure when attempting to publish pending products from Business Central to DynamicWeb 10. The connector establishes a connection to the DW10 instance successfully and can read data from its database, but the sync fails at product creation time with a duplicate key error on ProductName.

We tried going into the attribute mapping in the PIM connector and enabling / disabling the mapping for the ProductName field but the same error always occurs.

Environment

DW instance URL: advania-vefverslun.test.lisa.is

DW version: 10.22.9

BC version: IS Business Central 27.4 (Platform 27.0.46893.0)

PIM Connector version: 1.1.1.0

Error Message

The JSON object already contains the key 'ProductName'.
