Lesson 25.2: Crashes when I use assertions (assert())

**Describe the bug**
I just added two assertions in my code for exhaustiveness and editor printed this error:
```
Oh no! The script has an error, but the Script Verifier did not catch it
```

**To Reproduce**

Run this code:
```gdscript
func add_item(item_name, amount):
assert(!item_name.empty())
assert(amount > 0)
inventory[item_name] += amount
```

**Expected behavior**
I expected no error raised
