what's wrong with it?

(wrong screenshot)
So here's the code and the photo
'shield':
material: shield
slot: 4
priority: 3
update: true
banner_meta:
- 'BLACK;BASE'
- 'LIGHT_BLUE;RHOMBUS'
- 'BLUE;CIRCLE'
- 'BLACK;CROSS'
- 'BLACK;GLOBE'
hide_attributes: true
display_name: ''
lore:
- ''
view_requirement:
requirements:
left_click_commands:
- ''

so the banner and the code are different

The patterns had different names in 1.16.5.

Try these ones https://helpch.at/docs/1.16.5/org/bukkit/block/banner/PatternType.html
