Submit Extrinsic error by Creating ExtrinsicPayload and sign

I can’t make a transfer successfully, so I tired to generate extrinsicPayload and sign without creating signerPayload, but submitted extrinsic failed, could you please help me ? here’s the code and key pair:

it('totally-offline', async () => {
   const wsProvider = new WsProvider('wss://westend-rpc.polkadot.io')
    const from = '5FA5GKjtaCYHRhLtJ8bWhA1zP137PzTMmiDw8nfb5wDXSyGD';
    const to = '5Dgq3axpAPE7nUDKdhsxfvHKjBiRTwCQJesfxZ2z12b91TC3';
   const keyring = new Keyring({type: 'ed25519'});
    const pair = keyring.addFromUri(****)


    const api = await ApiPromise.create({provider: wsProvider});
    const nonce = (await api.query.system.account(from)).nonce.toString();
    const genesisHash = api._genesisHash.toString();
    const version = api.extrinsicVersion;
    const runtimeVersion = (await api._rpc.state.getRuntimeVersion());
    const header = await api.rpc.chain.getHeader();

    let current = header.number.toString()

    let registry = new TypeRegistry();
    let decorated = new Decorated(registry, metadataStatic);
    new Metadata(registry, metadataStatic);

    let tx = new Extrinsic(registry, decorated.tx.balances.transfer(to, 100));
    let era = registry.createType('ExtrinsicEra', {current: current, period: 900});


    let data = {
        address: from,
        blockHash: genesisHash,
       // blockNumber: '',
        era: era,
        genesisHash: genesisHash,
        method: tx.method.toHex(),
        nonce: nonce,
       // runtimeVersion: runtimeVersion,
       // signedExtensions:signedExtensions,
        specVersion: runtimeVersion.specVersion.toString(),
        tip: '',
      //  transactionVersion: runtimeVersion.transactionVersion.toString(),
       // version: version
    }

    let extrinsicPayload = new ExtrinsicPayload(registry, data, { version: 4 });

    const {signature} = extrinsicPayload.sign(pair);
    console.log('signature', signature)

    let verifySignature = hex.hexToU8a(signature).subarray(1)
    const verifyData = extrinsicPayload.toU8a(true);
    let verifyResult = pair.verify(verifyData, verifySignature);
    console.log('verifyResult', verifyResult)
    
     tx.addSignature(from, signature, extrinsicPayload);

     const hash = await api.rpc.author.submitExtrinsic(tx.toHex()
     console.log(hash.toHex())
    process.exit();
});

And always got the error: 1002: Verification Error: Execution(Wasmi(Trap(Trap { kind: Unreachable }))): RuntimeApi("Execution(Wasmi(Trap(Trap { kind: Unreachable })))

I don’t know what the problem is Can you please run my unit test and told me the result? thank you very much!
