Created seeds for vanilla item but item doesn't output

[kyjz91]

Seeds created based on vanilla items are normally planted and grown. However, when you try to harvest them after they grow, the vanilla item doesn't output and it works as an item error.

It may be insufficient by using a translator.
Are the items below described in the guide now unavailable?
<(optional) You can produce vanilla items. Instead of a named object you will use the objects ID number and not include a corresponding Objects folder.>

I know that the item code has changed since the 1.6 update.
Can't I quote vanilla items now because of this?

I'm asking you again because I'm experiencing the same inconvenience with the question left by another user.
The questions left by this user are as follows.

Can anyone tell me how to use the “Product” command to select information from the original game files?
I mean, for example, in the mod “Lost Trees and Crops”.
We have part of the code:
{ “Name": “Daffodil”,
"Product": 18,

....and it no longer works. The seeds do not produce a crop.

Please help
