Shopify Facebook App error "another item with the same retailer id was already uploaded...

[donnamac]

We are getting products erring out with this message

   "another item with the same retailer id was already uploaded to this catalog"

We are getting it on products from retailers we have carried for a long time.  
I have tried to report it via the 'report a problem' function with no results.

Can anyone shed any light on what causes this error and how to address it?
The product still gets sent to Facebook, so I am not sure how to 'clear' it in Shopify Facebook app?  The product is not flagged with an error in Facebook.

Thanks

Exactly!

I'm having the same problem!

I have a theory that there might be a 12-character limit and if the first 12 characters are the same on multiple items it throws an error. Just a theory.

I just don’t see how that can be as I have multiple brand new products with different names. I did reword and am trying to push through to Facebook again. We’ll see.

I was referring to the SKU. Not sure if Facebook keys off of that. I
noticed when I edited a sku one of the ones that was stuck went through.

Thanks. I’ll check it out

Thank you!  That was exactly the problem for me...duplicating a product.

I started off with a few new items getting this error but now old items are creeping up on my list.

I think I figured out the solution, I duplicated the product that was giving me the error and then deleted the product that was giving me the error. I was then left with the duplicated product and now that product isn't giving me any errors

Is there any update on this?

I have the same issue and i dont have any other items in my shop... its impossible for me to have duplicates because I literally just made the shop..
