So I should get a gold star - I still don’t know WHY the import is failing, but I now have two files that show the issue. I am sending them to the customer support email.
One file I’ve replaced all my keywords with the following (and this file does not import):
The other I’ve replaced all my keywords with the following (this file imports correctly):
As you can see, the only difference is the length of the keyword name. The “id” value changes based on the actual keyword needed and corresponds to the custom keyword id that I’ve set up already.
Incidentally; it doesn’t appear the XML import even pays attention to the actual keyword (value) string. It only goes off the id … hence the workaround right now is to put nothing in the keyword string. Which works about 99% of the time.
Hopefully from the two files I am sending you can ascertain the issue as it’s driving me crazy (and causing a import headache).
