Solana: Error when fetching pool keys from Raydium: “a bytes-like object is required, not ‘solders.account_decoder.ParsedAccount’”

Error Fetching Pool Keys from Raydium in Solana: “a bytes-like object is required, not ‘solders.account_decoder.ParsedAccount'”

As a user of the Raydium decentralized exchange (DEX) using Python, you’re likely familiar with its API and functionality. However, when interacting with the Solana node, you may encounter an error that seems to be related to fetching pool keys from the Raydium protocol.

The error message “a bytes-like object is required, not ‘solders.account_decoder.ParsedAccount'” suggests a problem with the data type of the solders.account_decoder.ParsedAccount object. This object is likely used to fetch account information from the Solana node, but the error indicates that it’s expected to be a byte array instead.

To troubleshoot this issue, let’s dive into the code and examine the possible causes:

Invalid Data Format: The error message implies that the data being fetched is not in the correct format. Make sure you’re fetching the correct fields from solders.account_decoder.ParsedAccount. Check your code to ensure you’re only fetching the necessary fields.

Incorrect Code Structure: Review the way you’re constructing and sending the API request. Ensure you’re using the correct parameters, headers, and encoding for your data.

Network Issues

: Although less likely, network problems can cause issues with API requests. Check your internet connection, ensure it’s stable, and try reconnecting to the Solana node.

To resolve this issue, I recommend the following steps:

Check the Raydium API Documentation: Review the official Raydium documentation to confirm how to fetch pool keys from the protocol.

Verify Data Format and Code Structure: Double-check your code to ensure it’s correctly constructing and sending the solders.account_decoder.ParsedAccount object.

Test with a Different Method: Try fetching pool keys using another method, such as the Solana SDK or an alternative API endpoint.

If none of these steps resolve the issue, I’ll be happy to help you debug further or provide additional guidance on how to tackle this problem.

Example Code

Here’s an example of how you might fetch pool keys from Raydium in Python:


import solana_sdk







Initialize the Solana API client

sol = solana_sdk.SolanaClient()



Define the API endpoint and parameters

api_endpoint = "

params = {

    "pairId": "SOL/LINK",

    "keyType": "account_key",

    "action": "fetchAccount"

}



Fetch pool keys from Raydium

response = sol.get_api_data(api_endpoint, params)



Parse the response as JSON

data = json.loads(response.decode())



Extract the pooled account data

pooled_account = data["pools"][0]["pools"][0].get("account")



Print the pooled account data

print(pooled_account)
