I used data-migration-tool to migrate my store from 126.96.36.199 to 2.1.14, but after the migration, I find I can't open "edit" page of any existing product. The following error message show up:
There has been an error processing your request.
The configuration parameter "formElement" is a required for "" field.
Error log record number: 1495859023951
(Yes, there is nothing in the second quote mark)
Also, I tried to add new product, with new attribute set, but when I configured it and click "save", it shows:
Attribute with the same code already exists.
Anyone knows how to solve it?
You have duplicate attribute with the same code value in the product attributes.
Find duplicate attribute from Admin->Stores->Attributes->Product and delete one attribute and try to save product.
Note: Make sure first you check that that attribute is not used with any product.

I checked my Product Attributes, but didn't find any duplicated attribute code.
Is there any other problem can cause this issue?
