i am unable to find confirmation number in transaction receipt

[ghost]

async function fund() {
    const ethAmount = "0.027"

    console.log(`Funding with ${ethAmount}...`)
    if (typeof window.ethereum !== "undefined") {
        // provider / connection to the blockchain
        // signer / wallet / someone with some gas
        // contract that we are interacting with
        // ^ ABI & Address

        const provider = new ethers.BrowserProvider(window.ethereum)
        const signer = await provider.getSigner()

        const contract = new ethers.Contract(contractAddress, abi, signer)

        try {
            const transactionResponse = await contract.fund({
                value: ethers.parseEther(ethAmount),
            })
            // hey, wait for this TX to finish
            await listenForTransactionMine(transactionResponse, provider)
            console.log("Done!")
        } catch (error) {
            console.log(error)
        }
    }
}

function listenForTransactionMine(transactionResponse, provider) {
    console.log(`Mining ${transactionResponse.hash}...`)
    // create a listener for the blockchain
    return new Promise((resolve, reject) => {
        provider.once(transactionResponse.hash, (transactionReceipt) => {
            console.log(transactionReceipt.confirmations)
            resolve()
        })
    })
}

if I try to return and log confirmation number in listener function, it is returning some kind of function as a plain text....

The number of confirmations is async, and confirmations is a method, so you can use await receipt.confirmations() to get the current number of confirmations.

Does that make sense?

Kinda

[ghost]

function listenForTransactionMine(transactionResponse, provider) {
    console.log(`Mining ${transactionResponse.hash}...`)
    // create a listener for the blockchain
    return new Promise((resolve, reject) => {
        provider.once(transactionResponse.hash, async (transactionReceipt) => {
            await transactionResponse.wait(1)
            console.log(
                `Completed with ${await transactionReceipt.confirmations()} confirmations..`
            )
            resolve()
        })
    })
}

THANKS !

When using once(), confirmation() returns 0 instead of the expected 1.

I tried replacing once() with on() to see if it resolves the issue.

  return new Promise((resolve) => {
    // provider.once(transactionResponse.hash, async (transactionReceipt) => {
    //   console.log(
    //     `Completed with ${await transactionReceipt.confirmations()} confirmations`,
    //   )
    //   resolve()
    // })
    const listener = async (transactionReceipt) => {
      const confirmations = await transactionReceipt.confirmations()
      console.log(`Completed with ${confirmations} confirmations`)
      if (confirmations >= 1) {
        resolve()
        provider.off(transactionResponse.hash, listener)
      }
    }
    provider.on(transactionResponse.hash, listener)
  })

Is this the correct approach, or is there a better way to handle this case?
