Resolve the non-iterable Smart Object error by flattening nested Smart Objects inside your packaging PSD template.
So this error, this.state.design file is not iterable means that whenever you work with a smart object template this smart object layer is not iterable means this cannot be changed to a new smart object. This error could occur uh cause of multiple issues. In this template we will see what is the issue and try to fix it.
If we investigate this smart object layer, I double click on this smart object layer, it opens up a new tab. And if you remember, if you see, this again is a smart object layer. So we have a smart object nested inside a smart object. And perhaps this is the reason why this error was popping, that this smart object layer cannot be iterable. The way to fix this, we’ll have a smart object here.
but over here we do not want to the smart object I’ll just press RESTORIZE this and see if this helps remove the smart object layer now we have removed the smart object layer I’ll save it and then I’ll close it with CTRL W now if I open this smart object this is flattened so follow this step and I think this error will be resolved thank you
The error “this.state.designFile is not iterable” happens because Bulk Mockup cannot replace the Smart Object in your packaging PSD file. In almost every case, this is caused by a nested Smart Object, a Smart Object inside another Smart Object.
Bulk Mockup can only replace a top-level Smart Object, so we must flatten the inner one. Below is the correct, step-by-step method to fix this:
To understand how to replace a nested smart object, check this tutorial.
The “not iterable” error occurs because of nested Smart Objects. Flattening the inner Smart Object instantly resolves the issue and makes your PSD compatible with Bulk Mockup.
This error shows up when Bulk Mockup encounters a Smart Object layer that cannot be replaced because it contains another Smart Object inside it. Since the plugin cannot iterate through nested Smart Objects, it rejects the operation and shows this message.
Double-click the Smart Object layer inside your PSD. If the new tab that opens also contains a Smart Object instead of a flat design layer, it means your template uses nested Smart Objects, which Bulk Mockup cannot process automatically.
Simply rasterize the inner Smart Object layer so it becomes a normal pixel layer instead of another Smart Object. Saving and closing the tab will flatten it permanently, allowing Bulk Mockup to replace it without producing errors.
Rasterizing converts the Smart Object into a fixed pixel layer. For mockup purposes, this doesn’t affect output quality, since Bulk Mockup will replace this layer entirely with your incoming design file.
Yes, although nesting is the most common cause. The error can also appear if the design layer is corrupted, locked, or incorrectly labeled. Fixing the nesting usually resolves the issue, but rechecking the template structure is always helpful.
