Issue type:

• 🐛 Bug

Steps to reproduce the problem:

1. Make a list variable of type any, but with itemstacks in it, or it can just be empty. (I'm not sure if list is intended to be able to have type any)
2. Make an empty ingredients variable
3. Make a variable card using Ingr.with_items and the aforementioned list and empty ingredients
4. Try putting the card in a proxy block
5. Try putting the card in a display panel

About list of type any:
The easiest way of making one is probably using an NBT edit mod to edit a constant variable card?
I'm not sure if a list of type any is intended behavior, if not, I'll make another issue and report how I got one of these through normal operations.

Short description:

(See the "Steps to reproduce" section for context)
The list variable of type any is the key here, with a normal itemstack typed list it works just fine.
The resulting variable in a proxy block or similar shows an empty ERROR in the gui (also shows up in the blockentity NBT as an empty (errors: {collection: []})), but no error is generated.
The resulting variable in a display panel crashes the server when a client has the gui open, with out the gui open you get a The part integrateddynamics:display_panel at position BlockPos{...} was errored and is removed.

Sure, lists of type any are possible. You can even define this through the LP.

Oh yeah. I never clicked the next button enough times to see it can be Any.

FYI, temporary workaround for this issue is to do a concat of an empty list of type itemstack and the any-typed list to "cast" the list to the itemstack type.

But is there a proper way to cast it into a typed list? Or is this the best way to do it?

No, once a list has been created, there's no way to change the type.
In theory, an operator for that could be created, but that depends if the need for that really exists.

Wow, what a fast response.
Still not sure if a list of type any is intended behavior?
If so, then is there a proper way to cast the type of the list?

Thanks for reporting!
