how to summon mob with saddle(pig)

i was following this 1 year old 1.21 how to make your first datapack tutorial by quackleb and at the end he made a pig spawn  and then made him ride that pig in like 4 lines, i tried that and everything worked but the saddle on the pig for some reason?
playsound minecraft:entity.pig.saddle
summon pig ~ ~ ~ {Saddle:1b}
ride @s mount @n[type=pig]
attribute @n[type=pig] movement_speed base set 10
item replace entity @s weapon.mainhand with carrot_on_a_stick
this is my current code everything else works here but the saddle
