Issue with token swap in CPMM pool: TransactionExpiredBlockheightExceededError

[6otah]

Hello,

I am encountering an issue with token swaps through the CPMM pool: error TransactionExpiredBlockheightExceededError. I noticed similar issues reported previously, where increasing the priority fee was suggested.

There are SOL, WSOL, and the pool token in my wallet. In the code, I set the input amount to 0.005 SOL with const inputAmount = new BN(5_000_000), and the priority fee to 0.002 SOL as follows:

computeBudgetConfig: {
  units: 600000,
  microLamports: 2_000_000_000_000,
},

Despite this, the transaction string is formed, and the transaction expiration error is returned. This issue also occurs when attempting to swap in the reverse direction, using:

const inputAmount = new BN(10_000_000_000_000); // 10_000_000 with 6 digits
const inputMint = poolInfo.mintB.address;

Am I setting the correct values? What else can I do for testing to resolve this issue?

could you provide pool id and full code to here? after some testing demo works for both side swapping

after did some mintA -> mintB, mintB -> mintA testing, all tx went through smoothly, so this might caught by network congestion or your rpc's issue, provide the code I tested with mintB -> mintA Tx. mintA -> mintB: https://solscan.io/tx/2Xx5GaUvGnNcigXH4ZMdaDAxYdoitfVYgnykiD8y4ds7nbdijYxe7HZfVaULogZRABow8mqBXwzonh8W9bvkBkzx
