Hi @Stoyan_Vatov,
I was able to make it work - although not perfectly.
In the instagram module for carousel posts I configured 6 images. The Woocommerce products usually have up to 6 images.
The issue is, not all products have 6 images, some have less. And that creates an issue. The module expects image_url input, but if the cell is empty the module stops working and shows the error message.
If I lower the number of images to 4 in the Instagram module, it seems to work for most of the products. But still not quite reliable… also very tricky to get my head around. Hoped that zero / no code platforms like make would be a little easier to use 
Many thanks for your help anyway.
