The bug

If an item is given to the player with an invalid model component, an error is not printed to the game log. This is unlike what happens with resource packs if broken models are present.

How to reproduce

1. /give @s stick[item_model="minecraft:nonexistent_model"]

2. Check the game log

Expected results

Since the game failed to locate a valid model for this item, an error would be logged.

Actual results

There is no error recorded.
