ExtensionNotFound

“Extension not found in account data”

The instruction needs an extension that this mint or account does not have.

Common causes

  • Calling an extension-specific instruction (for example TransferCheckedWithFee, UpdateMetadata, SetTransferFee) on an account without that extension.

How to fix it

  • Check the extensions on the account with the Token-2022 extension checker on this site and only use instructions the account supports.
