[Error] Evolution error

[RyuKunMR]

Hello, I'm doing my first Pokémon game and I had an error when my Fartfetch'd evolves into Sirfetch'd when doing 3 critical hits during combat, the message is as follows:

---------------------------

If anyone can help me thank you very much.

How is the evolution method defined in the scripts?
