This might actually be an issue in geth

ethereum/go-ethereum#25464

Its not an issue in geth, it means your node isnt correctly configured for the merge:

[porktonkatsu]

Ah yea, this is the step that was missing https://docs.prylabs.network/docs/execution-node/authentication

Closing then. Thx

Just leaving this here in case anyone else runs into this. I got this error when running geth on goerli with syncmode=light . The error message on both ends is cryptic, but switching geth to syncmode=snap solved it for me.

geth light client missed that function
has been fixed upstream in current geth master :
