You’re right. The error occurs when trying to create the Merchant Key.
node -e “const btcpay=require(‘btcpay’); new btcpay.BTCPayClient(‘https://lightning.filipmartinsson.com/’, btcpay.crypto.load_keypair(Buffer.from(’<BTCPAY_KEY>’, ‘hex’))).pair_client(’<BTCPAY_PAIRCODE>’).then(console.log).catch(console.error)”

The course was great, thanks a lot Filip!

I want to build my own website with a Lightning App using the knowledge I’ve just learned. I live in a small place and don’t really want to run a bitcoin node at home 24/7. Is there a way I can maybe run a light client node on AWS for cheaply? If you have any advice please let me know. Cheers

Sorry for the slow response. I have been sick for the past week.

Maybe a stupid question, but you are replacing the <BTCPAY_KEY> and <BTCPAY_PAIRCODE> with the actual codes right?

#45

Thank you very much! Yeah you can definitely run it on aws. You can check out this blog post for guidance: https://medium.com/andreas-tries-blockchain/bitcoin-lightning-network-1-can-i-compile-and-run-a-node-cd3138c68c15

Hi no worries, hope your getting better! Yes i replaced the BTCPAY_KEY and BTC_PIARCODE with the right codes, just didn’t want to post them in the forum. I have also tried both variants of code (original on GitHub and the correction for windows) and also tried to reset everything and started from scratch, unfortunately so far without success.

#47

Do you get the same error now regardless of which script you use?

Could you please paste your script into a text file (including the keys) and send that file to me in a DM here in the forum? I want it in a text file in order to avoid the forums own formatting of certain special characters.

Just a disclaimer for everyone: In normal circumstances you should never send your keys to anyone that asks you, including me. These are not private keys that are used for anything valuable. They are just a random generated keypair from my lightning server.

Hey, I’m getting a RequestError when trying to get the merchant token. I’m running BTCPay locally for development and running the following command:

node -e “const btcpay=require(‘btcpay’); new btcpay.BTCPayClient(‘https://192.168.0.12:23001’, btcpay.crypto.load_keypair(Buffer.from(‘XXXX’, ‘hex’))).pair_client(‘XXXX’).then(console.log).catch(console.error)”

Error:

name: ‘RequestError’,
message: ‘Error: write EPROTO 4347239872:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:…/deps/openssl/openssl/ssl/record/ssl3_record.c:332:\n’,

Any idea what’s causing this?

Oh found it, I’m not using a secure connection so https should be http.

Great, I’m glad you solved it :slight_smile:

#51

what is your lightning public key (its not posted above the video) ?

#52

You shouldn’t need my public key? You generate your own keypair with the paircode.

#54

Hey @filip I’m stuck with the following error: TypeError: Cannot read property ‘fromRed’ of null - while trying to generate the Merchant key.

I am running the recommended script for Windows users - exact the same case as for @KnutKurbel. What’s the solution to this error? I notice there’s been a debate but no clear solution has been given yet.

Hi @Karolis_Abramavicius. In my case I had to remove the < > around the keys. That helped to create the merchant keys.

Hi.
I see the error message says that "no wallet has been linked to the BTCPay Store. Have you checked that the settings in your BTCpay Store is correct?

I have followed all the procedure in the video. Do I need to do something extra?

I also see that you get the error «unauthorized access to API, premium plan needed» I remember i got the same error when I tried to show BTC_NKR instead of BTC_USD.

Is this the first time you run the code? Or did it work before?
Can you post a screenshot of your code? Maybe we can spot the error?

It is my first time to run the code and I am using windows.
Here is the code in the invoice.js .
Thanks a lot.

var express = require(‘express’);
var router = express.Router();
const BTCPAY_PRIV_KEY = “”;
const BTCPAY_MERCHANT_KEY = “”;

// Initialize the client
const btcpay = require(‘btcpay’)
const keypair = btcpay.crypto.load_keypair(new Buffer.from(BTCPAY_PRIV_KEY, ‘hex’));
const client = new btcpay.BTCPayClient(‘https://lightning.filipmartinsson.com’, keypair, {merchant: BTCPAY_MERCHANT_KEY})

/* get & verify invoice. */
router.get(’/:id’, async function(req, res, next) {

});

/* Create invoice. */
router.post(’/’, function(req, res, next) {
var dollarAmount = req.body.amount;
client.create_invoice({price: dollarAmount, currency: “USD”})
.then(function(invoice){
console.log(invoice);
res.render(“invoice”, {invoiceId: invoice.id})
})
.catch(err => console.log(err));
});

module.exports = router;

HI.
I`ll take a look at it and come back to you. Can you check the settings in btcpay store and see if everything is correct in the mean time?
