Unable to get transaction status

[Japelino]

I have a few L2->L1 transaction hashes that I would like to know if they're claimed/claimable/settled/pending.
However "status" always returns the error: "invalid BigNumber value (argument="value", value=undefined, code=INVALID_ARGUMENT, version=bignumber/5.7.0)"

1. First try:

const fetchEventStatus = async (txHash) => {
    const receipt = await l2Provider.getTransactionReceipt(txHash);
    const log = receipt.logs[0];
    const msg = L2ToL1MessageReader.fromEvent(l1Provider, log);
    const status = await msg.status(l2Provider); // Throws error
}

2. I tried to parse the log using ArbSys but I get the same error:

const fetchEventStatus = async (txHash) => {
    const receipt = await l2Provider.getTransactionReceipt(txHash);
    const log = receipt.logs[0];
    const ArbSysContract = new Contract("0x0000000000000000000000000000000000000064", ArbSysABI, l2Provider);
    const parsedLog = ArbSysContract.interface.parseLog(log);
    const msg = L2ToL1MessageReader.fromEvent(l1Provider, parsedLog);
    const status = await msg.status(l2Provider); // Throws error
}

EDIT:
3. Also tried the following:

const fetchEventStatus = async (txHash) => {
    const receipt = await l2Provider.getTransactionReceipt(txHash);
    const eventsData = await L2ToL1MessageReader.getL2ToL1Events(
      l2Provider,
      { fromBlock: receipt.blockNumber-1, toBlock: receipt.blockNumber },
      undefined,
      undefined,
      receipt.hash,
    );
    const event = eventsData[0];
    const message = L2ToL1MessageReader.fromEvent(l2Provider, event);
    const status = await message.status(l2Provider); // Throws error
}

This makes status throw a different error: "call revert exception [ See: https://links.ethers.org/v5-errors-CALL_EXCEPTION ] (method="latestConfirmed()", data="0x", errorArgs=null, errorName=null, errorSignature=null, reason=null, code=CALL_EXCEPTION, version=abi/5.7.0)"
