Magento 2.1.8.
I firstly successfully use rest API to create a parent item (configurable item). Then I use the API to create a child item (simple product item) under the parent item. The Magento 2 backend gives me "Products "%1" and "%2" have the same set of attribute values." error.
See following logs:
1. successfully create a parent item:
ACTION:
PUT
URL:
/index.php/rest/V1/products/8100
HEADER:
Content-Type:application/json
Accept:application/xml
............
RESPONSE:
HTTPCODE:
200
RESPONSE:
<?xml version="1.0"?>
<response>
<id>361</id>
<sku>8100</sku>
...........
Then I try to add a child item:
ACTION:
POST
URL:
/rest/V1/configurable-products/8100/child
HEADER:
Content-Type:application/json
Accept:application/xml
REQUEST:
{"childSku": "8116"}
RESPONSE (with error):
HTTPCODE:
400
RESPONSE:
<?xml version="1.0"?>
<response>
<message>Products "%1" and "%2" have the same set of attribute values.
</message>
<parameters>
<item>372</item>
<item>337</item>
</parameters>
</response>
It used to work on 2.0.11, I upgraded to 2.1.8 then lots of my API calls are not working. This is just too hard to integrate other software to Magento 2.
