Flashbot bundle is not included because "isSendToMiners" is false?

[Neronjust2017]

I'm trying to send a flashbot Bundle with several transactions. I use the following code to sign and send a bundle:

 const signedTransactions = await flashbotsProvider.signBundle([
    {
      signer: MyWallet,
      transaction: firstTx
    },
    {
      signer: MyWallet,
      transaction: secondTx
    },
    {
      signer: MyWallet,
      transaction: thirdTx
    }]);
    const targetBlockNumber = block.number; 
    const simulation = await flashbotsProvider.simulate(
      signedTransactions,
      targetBlockNumber + 1
    )

    console.log(simulation);
    console.log("bundleHash: ", simulation.bundleHash);

    for (var i = 1; i <= 10; i++) {

      console.log(">>>>>> ", i);

      const bundleSubmission = await flashbotsProvider.sendRawBundle(
        signedTransactions,
        targetBlockNumber + i
      )
      console.log('bundle submitted, waiting', bundleSubmission.bundleHash)

      const waitResponse = await bundleSubmission.wait()
      console.log(`Wait Response: ${FlashbotsBundleResolution[waitResponse]}`)
      if (
        waitResponse === FlashbotsBundleResolution.BundleIncluded ||
        waitResponse === FlashbotsBundleResolution.AccountNonceTooHigh
      ) {
        console.log('Bundle included!')
        process.exit(0)
      } else {

        console.log(">>>", simulation.bundleHash);

        console.log({
          bundleStats: await flashbotsProvider.getBundleStats(
            simulation.bundleHash,
            targetBlockNumber + 1,
          ),
          userStats: await flashbotsProvider.getUserStats(),
        })
      }
    }

The simulation is successful. However, In order to ensure that the bundle can be included, I for loop 10 times to send a new bundle in case the previous bundle fails. It seems that the bundles are not included because they are not sent to the miners(isSentToMiners is false). Why does this happen?

Hi Thank you for your report. After the merge, the field isSendToMiners will be omitted, meaning it should always be set to false. Please use V2 stats endpoints. so inclusion is not related to this field.

Hi, thanks for your answer! I tested it again and this time I set the priority gas price to 500Gwei on Goerli to make sure builders will be likely to consider these bundles. I sent bundles in turn to target blocks from 8560814 to 8560816. As you can see, the first bundle was considered and sealed by some builders. According to https://collective.flashbots.net/t/flashbots-bundle-relay-api-upgrades/896, a bundle being sealed indicates a builder built a full block containing that bundle. Since it had been successfully sealed on block 8560814, why did it not be included? Is it the competition between the builders that causes the validators didn't select these blocks? If I further increase gas price, would that increase the probability of being included in the first block? Or because of the network problem, it is too late when builders received the bundle. In this case, reducing the network delay may solve the problem. Looking forward to your opinion. Thanks!

@Neronjust2017, hi, I am currently facing the same issue, i was wondering if you managed to solve it
