Facing issue here specifically :
export const getPythPriceFeedAccount = (provider: AnchorProvider, shardId : number = 0): PublicKey => {
const pythSolanaReceiver = new PythSolanaReceiver({
connection: provider.connection,
wallet: provider.wallet,
});
const priceFeedAccount = pythSolanaReceiver.getPriceFeedAccountAddress(shardId, GOLD_USD_PRICE_FEED_ID);
return priceFeedAccount;
};
