Fresh KDS error: Cannot read properties of undefined (reading 'split')

Hi this is the error I get

I’m also running into this issue while testing the Shopify + Fresh KDS integration.  I’ve pinned it down to orders which contain at least one product that does not have a variant.  If an order contains only products with variants, it gets correctly pushed to the KDS.  If at least one product does not have a variant, the ‘Line Items Variant Title’ modifier (circled below) will contain empty fields, which I suspect is what the split (or more accurately it’s return value access) is upset about. In that test order, the first two line-item products do not have variants and the third does.

The official response in this thread suggests that the solution involves working with Fresh KDS, which may be because they require that additional modifier field for each item.  If that is the case, at least an interim solution might be to simply default any undefined variants/modifiers to ‘Default’ or an empty string to make Fresh KDS happy.

Please advise on whether an interim solution is possible and if there’s any progress towards an ETA. 

Looks like my reply got lost in moderation somewhere along the way.  Trying again…

I’m new to Zapier but the ‘Text in Formatter - Default’ workaround doesn’t appear to be an option due to the null line-items being dropped from the Line-Item object.  You can reproduce it by adding a ‘Text to Line-Item’ transform with text ‘,,Small’ and then try the ‘Default’ workaround or a ‘Line-Item to Text’ transform to get back to the original ‘,,Small’ text.  In both cases, a test shows that the null values are missing from the Line-Item object.  The test output for the first ‘Text to Line-Item’ transform does return the correct null values but once the line-item object is accessed later, they’re gone and the only element in the list is ‘Small’.  This appears to be known behavior based on this old thread, but it doesn’t look like I can use the workaround there since I don’t have control over the creation of the line-item object.

Unless I’m misunderstanding, this would suggest that the issue may actually be on your end.  Unless your backend is keeping track of the null modifiers under the hood so that they can be passed to Fresh KDS with their corresponding item, the association between the modifier and the item will be lost once the null modifiers are dropped and the modifier line-item array no longer aligns with the other line-item arrays.

Is my understanding correct of how null line-items are handled?  If the null modifiers are indeed somehow being passed to Fresh KDS, is there a way I can access them from the line-item object so that I can try mapping them to a new line-item with default values?

Thanks.

Looks like it’s working.  I’m now able to successfully send all orders to Fresh KDS.  Thanks for the assist!
