Errors when Importing products in Magento 2.4.5-p1

Magento 2.4.5-p1

I exported products from Magento version 2.4.2-p1. I then go to import the CSV file into my Magento 2.4.5-p1. The check goes mostly OK and it says it can import the data. Then, I click to do it, it takes a long time and comes back with a few minor Errors such as:

Category ” bla/blablabla” has not been created. URL key for specified store already exists.

But it seems to have 2 major Errors:

Imported resource (image) could not be downloaded from external resource due to timeout or access permissions in row(s): 355, 419, 604, 629, 1460, 1509, 1600, 1733, 2010, 2015, 2051, 2054, 2058, 2263, 2387, 2390, 2393, 2524, 2527, 2678, 2679, 2682, 2685, 2688, 2691, 2694, 2697, 2700, 2703, 2706, 2707, 2708, 2711, 2714, 2717, 2720, 2723, 2726, 2729, 2732, 2735, 2738, 2741, 2744, 2747, 2749, 2751, 2753, 2756, 2759, 2762, 2766, 2767, 2770, 2773, 2776, 2779, 2782, 2785, 2788, 2791, 2794, 2797, 2800, 2801, 2803, 2806, 2809, 2812, 2813, 2814, 2817, 2820, 2823, 2826, 2829, 2832, 2835

And on the bottom, it has this Error:

I googled the 2nd Error and it is talking about duplicates and how the duplicates have to be deleted. But I don’t understand this:

  • first of all – we did duplicate some products to use them in different websites/stores/storefronts but if they would have been identical, shouldn’t have Magento 2.4.2-p1 not even allow to save them?
  • second – how would you even have 2 same products with the same SKU? Is that even possible?

Any which way – what is the best process for me to follow to determine what the duplicates are and once I identify them, how to proceed?
