Assistance Required: Backend-Frontend Connection Error - subnet_not_found

actor is basically my canister (I’m using ic-use-actor library).

Using an agent like so…

const agent = await createAgent({
    identity,
    //host: HOST,
});

const { approve } = IcrcLedgerCanister.create({
    agent,
    canisterId: process.env.CANISTER_ID_ICP_LEDGER,
});

let approveArgs = {
    spender: {
        owner : Principal.fromText(principal),
        subaccount: []
    },
    amount: 1000000000000,
    expected_allowance: 100000000,
    fee: 10000
}

const data = await approve(approveArgs);
console.log(data);

…I’m gettting a Invalid certificate: Signature verification failed error. Any idea how to solve this one? (I was getting this error a few days ago - see here - this is why I tried to get creative and tried using actor)
