Testing zaps for this note… we made six attempts to⚡zap this note, at heliodex@stacker.news, over a period of 43 minutes. 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://stacker.news/api/lnurlp/Heliodex/pay ). Your server did not produce an invoice, thus the zap failed. The error we got was "could not generate invoice to customer's attached wallet". If you wanted to fix this... you could try a free Rizful account -- https://rizful.com ... when u have it set up, pls reply here so we can do this ⚡zap test again.
