@springrainroni make sure you have the most up to date IDL...checking this helped me solve this error

This error means the instruction you are trying to invoke does not exist on-chain. Possible reasons why:

  • The program was built but not deployed on-chain
  • The IDL could be out of date(either local or on-chain)
  • The instruction name could be invalid due to case conversion(https://github.com/coral-xyz/anchor/issues/736)
