Pathfinder 2E What Stat for Monks' Focus Ki Spells in Pathfinder 2e?

[Strider1973]

Hi everybody, just a simple question, probably more proper to a Q&A section:
Which Stat does a Monk use for her/his Focus Ki Spells? Charisma? Wisdom? I can't find the specific rule in the Core Rulebook: can you help me? What am I missing?
Thank you very much! Happy gaming and stay safe!

Official errata:

Page 157: In the Key Terms sidebar, under the Ki Spells
entry, add “and your key spellcasting ability is Wisdom”
to the end of the second paragraph.

Prior to the errata, I'd have argued for STR/DEX depending on which you picked as everywhere in Core class DCs is listed using the Key Ability for the class...I'd even argue this after the errata to keep them less MAD.

Just to make sure everything's crystal clear here:

The official intention has always been for Wisdom to power Ki, just like it has been for nearly every implementation of Monk in D&D ever.

While the errata adds the actual rule Paizo forgot to include in the first printing of the Core Rulebook, the example Monk build offered on page 161 (the Ki Monk) make it clear Wisdom was always intended to be the key ability for Ki powers.

ABILITY SCORES
Prioritize Strength. Wisdom empowers your ki spells,
Perception, and Will saves. Constitution and Dexterity
help your physical defenses.

(note my emphasis)

Paizo never intended Ki to be driven by anything else than Wisdom.
