Couldn't repro, but we did just bump the SDK to address some potential
To mitigate a possible a version mismatch between with nostr-tools gen secret, I updated the example to use the clink wrapped nostr-tools... i dont think this was the problem though otherwise the log would show an error about it
Potentially are race with clock skew since the sub is set up after the request, moved that around just in case
Update CLINK to 1.5.1
NPM registry seems to not be rendering the readme yet, but its on github... pasting it here jic
import { ClinkSDK, NofferData, generateSecretKey, decodeBech32 } from '@shocknet/clink-sdk';

// First, decode the offer string to get the relay and pubkey
const nofferString = 'noffer1qvqsyqjqxuurvwpcxc6rvvrxxsurqep5vfjk2wf4v33nsenrxumnyvesxfnrswfkvycrwdp3x93xydf5xg6rzce4vv6xgdfh8quxgct9x5erxvspremhxue69uhhgetnwskhyetvv9ujumrfva58gmnfdenjuur4vgqzpccxc30wpf78wf2q78wg3vq008fd8ygtl4qy06gstpye3h5unc47xmee6z';
const decoded = decodeBech32(nofferString);
if (decoded.type !== 'noffer') throw new Error('Invalid offer string');

// Create SDK instance with the decoded relay and pubkey
const sdk = new ClinkSDK({
  privateKey: generateSecretKey(), // Uint8Array
  relays: [decoded.data.relay],
  toPubKey: decoded.data.pubkey,
});

const request: NofferData = {
  offer: decoded.data.offer,
  amount_sats: 1000, // sats (optional for variable/spontaneous offers)
  description: 'coffee for bob', // optional, max 100 chars
  expires_in_seconds: 3600, // optional
  payer_data: { name: 'Alice' }, // optional
};
const receiptCallback = (receipt) => {
  console.log("got receipt", receipt)
}
sdk.Noffer(request, receiptCallback).then(response => {
  if ('bolt11' in response) {
    console.log('Invoice:', response.bolt11);
  } else {
    console.error('Error:', response.error);
  }
});

I noticed the example is using SendNofferRequest while the NPM snippet is using sdk.Noffer. Does that matter?
const handleGetInvoice = async () => {
    if (!decodedOffer) {
        alert("Offer data is missing. Please decode a new offer first.");
        return;
    }

    nofferInput.disabled = true;
    offerActions.style.display = 'none';
    resultHeader.textContent = 'Invoice';
    resultData.textContent = 'Requesting invoice...';

    try {
        const amountSats = amountInput.value ? parseInt(amountInput.value, 10) : undefined;

        // Use the CLINK SDK to send a request for an invoice from the offer provider.
        // This request is sent over Nostr and signed with our ephemeral client key.
        const response = await SendNofferRequest(
            pool, clientPrivateKey, [decodedOffer.relay], decodedOffer.pubkey,
            { offer: decodedOffer.offer, amount_sats: amountSats }
        );

        if ('bolt11' in response && typeof response.bolt11 === 'string') {
            resultData.textContent = response.bolt11;
            qrCanvas.style.display = 'block';
            QRCode.toCanvas(qrCanvas, response.bolt11.toUpperCase(), { width: 256, margin: 1 });
        } else {
            resultHeader.textContent = 'Error Response';
            resultData.textContent = JSON.stringify(response, null, 2);
        }
    } catch (error) {
        console.error("Error getting invoice:", error);
        resultHeader.textContent = 'Error';
        resultData.textContent = `Error: ${error instanceof Error ? error.message : String(error)}`;
    } finally {
        isInvoiceDisplayed = true;
        decodeOfferButton.textContent = 'Reset';
        decodeOfferButton.style.display = 'block';
        scrollIntoView();
    }
};

Shouldn't matter, they're the same... sdk one just handle creating the pool
