testing zaps for this note… we made six attempts to⚡zap this note, at wahl@btcpay.fiattolightning.de, over a period of about 1 hour. in each case, we found that your lightning address server did not respond correctly. (the failure point was when we did a get request to your specified callback url: https://btcpay.fiattolightning.de/BTC/UILNURL/pay/lnaddress/wahl ). your server did not produce an invoice, thus the zap failed. the error we got was "Lightning node could not generate invoice: Memo is too long". if you wanted to fix this... you could try getting a free rizful lightning address -- https://rizful.com ... if u get it set up, pls reply here so we can do this ⚡zap test again.
