(Question): Is it possible to disable the error for empty tags? OR detect whether a tag isn't empty?

[pm065]

I've set up a script for creating dynamic recipes for ores and metals. It relies on:

1. first generating tags for detected metal items like nuggets and ingots
2. then generating recipes from those by turning a recipe definition object into a string, using regex to replace '#forge:(type)/_' with '#forge:(type)/(metal)', then turning it BACK into an object to feed it into a recipe-object-parsing function I made.

The problem is this:

This approach means that sometimes an empty tag will be inserted into a recipe. KubeJS errors on this and refuses to go any further. As far as I know, this is not vanilla behaviour. In Forge, I'm pretty sure empty tags are replaced by barriers, so I was planning to simply use event.remove({input: "barrier"}) in a low-priority script to clean it up.

Accounting for KubeJS not allowing empty tags would require me to detect whether or not a tag exists. I'm not sure it's even possible. Is it plausible to do this? If not, would it be possible to disable this error somehow?

You should be able to do Ingredient.of('#tag').isEmpty() to check whether it's empty; I don't think there's a way to allow invalid Ingredients as empty by default ^^

Thanks! I'll probably have to restructure the script a bit, but it'll certainly be doable.
