The sepolia genesis state file from Github can not work

Sepolia genesis state from Github can not work.

I follow the guide to start geth and prysm, but the following error occurs:

could not load genesis from file: version=0x64653d22 not found in any known fork choice schedule: unable to find requested BeaconChainConfig

maybe the Sepolia genesis state from Github should be updated?

Perhaps someone from the prysm team can look into this? @jmozah or @kasey perhaps?

Same issue here

could not load genesis from file: version=0x22626570 not found in any known fork choice schedule: unable to find requested BeaconChainConfig

[Parithosh Jayanthi]

pinging @terencechain or @kasey to look into it perhaps?

[Alex Stokes]

did double-check and the state on GitHub matches the one from my local node

[kasey]

@alexshliu that fork version does not seem to match anything in in the chain config. Is it possible that you did not correctly download the genesis.ssz file? Here's the sha256 sum I see for reference:

$ sha256sum genesis.ssz

I used wget to download the genesis.ssz several times. Unlikely that the problem is due to downloading

[Parithosh Jayanthi]

Which one of the two are you running?

1. wget https://github.com/eth-clients/merge-testnets/raw/main/sepolia/genesis.ssz
2. wget https://github.com/eth-clients/merge-testnets/blob/main/sepolia/genesis.ssz

Because 1. will download the ssz file, 2. will download a webpage
