REPLACEMENT_UNDERPRICED Different nonce on each

[JR0210]

Hi,

I've been working on creating a retry function for buying/selling a token. The buy function can error out on the transaction wait function and never encounters any problems other than issues with gas/slippage which is fine.

Selling seems to encounter a problem though, I'm using a swapExactTokensForTokens function from the Pancakeswap router but each time the sell is called I seem to encounter this error - Error: replacement fee too low, ...., code=REPLACEMENT_UNDERPRICED.

I can see in the docs this can be due to attempting to replace a previous transaction and increasing the gas should work? Though I'm unsure why it would be classified as this since it's called again and the nonce seems different on each attempt?

This is the code for my retry function:

async function retry(fn, n) {
  for (let i = 0; i < n; i++) {
    try {
      console.log(`Attempt ${i+1}`)
      const result = await fn();
      console.log(result, 'Awaiting receipt...')
      const receipt = await result.wait();
      console.log(receipt, 'Receipt');
      if (typeof(receipt) === 'object' && receipt.status) {
        console.log('Transaction receipt');
        console.log(receipt);
        return receipt;
      };
      console.log(receipt, 'Failed');
      throw 'Status Failed';
    } catch {}
  }

  throw new Error(`Failed retrying ${n} times`);
}

Deadline is set to 2 minutes per transaction, gas varies but recently is remaining around 60 gas fee/2000000 gas limit if this helps.

Thanks

I have some images to prove this that I can post too.

This continues for 5+ retries until exiting the process from my code

Can you cut and paste the errors into the issue? I want to manually parse the payloads sent...

Let me know if you need any of the others too, transaction hash doesn't come back to anything seemingly

Edit: Some of the errors seem to return a transaction hash that exists though the error is different -

Already known means there is already a transaction on the network with the identical properties.

I am currently debating whether it should be an error or swallowed, leaning towards swallowed, but it is not a NONCE_EXPIRED error. Is this what you were seeing?
