Getting request expiry when signing transaction using a custodial wallet

[ayudh37]

While waiting for the transaction to be signed on the custodial wallet website (a multistep process that takes anywhere from 2 - 5 minutes and involves MFA), we have our dapp wait for the transaction hash.

The transaction eventually completes but our dapp, instead of always receiving the transaction hash, gets a request expiry error.

Here's the error:

{

arguments: [
Error sending payment:,

{
code: UNKNOWN_ERROR,
error: [Object],
message: could not coalesce error (error={ "message": "Request expired. Please try again." }, payload={ "id": 6, "jsonrpc": "2.0", "method": "eth_sendTransaction", "params": [ { "data": "0xa9059cbb000000000000000000000000cadd40db79afd14995903533391822ade149165b0000000000000000000000000000000000000000000000000000000ecac99270", "from": "xxx", "gas": "0xb5a7", "to": "xxx" } ] }, code=UNKNOWN_ERROR, version=6.15.0),

We're using reown with the EthersAdapter.

Here's our code:

  const sendPayment = async (
    recipient: string,
    amount: string,
    tokenAddress: string,
    decimals: number,
    keepAmount?: boolean
  ) => {
    const signer = await provider?.getSigner();

    const contract = new ethers.Contract(tokenAddress, tokenAbi, signer);

    const amt = keepAmount ? amount : parseUnits(amount, decimals);

    const tx = await contract.transfer(recipient, amt);
    const receipt = await tx.wait();

    return receipt;
  };

Is there a way to increase the timeout limit or something along those lines so that we don't get the request expiry error anymore?
