Hello, it keeps happening.
The problem is not when you include a GTIN, the problem is when the GTIN field is empty and you update or publish a product, which shows you the word ARRAY.
Afterwards, if you remove the word ARRAY, and you update again, it appears fine.
But of course, it’s a double work to have to delete it and publish twice.
I indicate the access keys in the private area.
Please let me know if you touch anything.
Thank you.
