parsePriceData not properly parsing account data

[danielkboyer]

Code in question

  const pricePublicKey = new PublicKey(oracle.priceAddress);
    const result = await connection.getAccountInfo(pricePublicKey);
    if (result !== null) {
      let { price, previousPrice } = parsePriceData(result.data);
      priceData = price || previousPrice;
          }

Error

Error: The value of "offset is out of range. It must be >= 0 and <= 126. Received 176

Node.js v20.10.0

I'm not sure why it's not able to parse the oracles data anymore.

Solution

const pythSolanaReceiver = new PythSolanaReceiver({
    connection,
    wallet: new NodeWallet(RAND_KEYPAIR),
  });
 const priceAccount =
        await pythSolanaReceiver.fetchPriceUpdateAccount(pricePublicKey);

if (priceAccount !== null) {
  priceData = priceAccount.priceMessage.price;
}
      ```

I'm starting to study programming on Solana and in your solution to the "parsePriceData" error, can you indicate where we should get or import "PythSolanaReceiver", "NodeWallet" and "RAND_KEYPAIR" from?
