How to create a liquidity pool on Raydium on Solana devnet?

Can anyone give me any advice on how to create an LP pool on the Solana devnet?

I planned this job for testing swaps between specific two tokens on the devnet using the Raydium protocol.

So, I need to create a swap pool on the devnet first. To achieve this, I did it like below.

First of all, to list on the serum market, I cloned the Raydium-Dex repository on my mac and changed the Serum dex's program id from the mainnet to the devnet, and I success registered on the devnet serum. (Custom token with SOL pairs) As a result, I got a serum market program id.

After that, I cloned the Raydium-frontend repository to create a liquidity pool. And modified wellknownToken.config.ts so that my custom tokens could be possible to create a new pool.

Finally, I could access the create pool UI from the localhost web UI. I clicked Initialize Liquidity Pool button on the UI and got a Toast message Create a new pool Transaction Sent apparently.

However, It is not worked well. Because I can not find the transaction hash on the Solscan website. I tracked the button's click event codes and I figured out one thing.

One of the result value of Liquidity.makeCreatePoolTransaction function has a null value, especially, feePayer.

const { transaction: sdkTransaction1, signers: sdkSigners1 } = Liquidity.makeCreatePoolTransaction({
        poolKeys: sdkAssociatedPoolKeys,
        userKeys: { payer: owner }
})
const testTx = await loadTransaction({ transaction: sdkTransaction1, signers: sdkSigners1 })
console.log('feepayer', testTx.feePayer?.toBase58()) // null

I felt this is not the preferred (good) way to create a swap pool on the Solana devnet, but I can not find a better way to achieve this task.

What am I missing? or What am I should read or learn? please give me some advice on how to do it to make it works.

Thanks.

It looks like the transaction created with Liquidity.makeCreatePoolTransaction hasn't been sent to the network, so it doesn't exist anywhere. Be sure to send and confirm the transaction before trying to load it. You can use something like:

const { transaction: sdkTransaction1, signers: sdkSigners1 } = Liquidity.makeCreatePoolTransaction({
        poolKeys: sdkAssociatedPoolKeys,
        userKeys: { payer: owner }
});
await sendAndConfirmTransaction(connection, transaction, [wallet]);

Note that this requires a connection to send and a wallet to sign. More info at https://github.com/solana-labs/solana/blob/9ac2245970de90af30bff9d1f7f35cd2d8f2bf6d/web3.js/src/util/send-and-confirm-transaction.ts#L18

You might run into other issues though, because the Raydium program isn't deployed to devnet: https://explorer.solana.com/address/675kPX9MHTjS2zt1qfr1NYHuzeLXfQM9H24wFSUt1Mp8?cluster=devnet
