could not find tx or effectiveGasPrice

Describe the Problem

I do swaps via command line, on uniswap v3 forks or also v2 forks. The transaction is done via command line script and it works, but often I don't get the receipt and get this error:

Error: report this; could not find tx or effectiveGasPrice

Happens often on Telos, chainId 40, but sometimes also on other chains. Can this be caused by the RPC?

Note: the transaction usually works. I check on block explorer and find it. Just my script throws this exception, which I also try to catch without success... the error is not caught. I mean I try to handle it via e?.message but the code crashes before reaching that part.

    try {
      const receipt = await (await method(params, options)).wait() // execute
    } catch (e) {
      let txNotFound = "could not find tx or effectiveGasPrice"
      if (e?.message?.includes(txNotFound) || e?.toString().includes(txNotFound)) {
        // Logger doesn't log it because I never arrive here
        Logger.error(`Error: could not find tx or effectiveGasPrice`)
      } else {
        throw e
      }
    }

So since the error tells me to report this, I'm reporting it ;)

Environment, this happens both if I use a hardhat task or a standalone nodejs script (without hardhat, getting the provider the usual way, via json provider).

Code Snippet

const options = { gasLimit, gasPrice }
const receipt = await (await router.swapExactTokensForTokens(params, options)).wait()

I got the same issue on metis chain too. Was trying to buy AraFi Token on hermes router. it is intermittent though and I cannot consistently reproduce it.

Do you have public endpoints for those chains? It is possible that those chains do not return it (or have renamed it) in their RPC. I need to be able to test it though, so pointing me to RPC endpoints to test with would be helpful :)

Try on Telos, but it doesn't happen all the time. Just from time to time...

Try this RPC:

https://mainnet-eu.telos.net/evm

As said, you may need to do many transactions to be able to reproduce this.
