hey @fishone
you are using the beta id for ETH/USD but I do not think you should do it.
beta ids are for hermes beta endpoint which is used only for Aptos testnet , Sui testnet or Near testnet
please try with this id instead 0xff61491a931112ddf1bd8147cd1b641375f79f5825126d665480874634fd0ace and this URL: https://hermes.pyth.network
