footer and author icon url not working - output shows it as iconUrl instead of icon_url

[dan-dr]

// add author
embedBuilder.setAuthor(new EmbedAuthor("Author", "https://example.com/png.png", "https://example.com"));

// ... later after creating a message
webhookMessage.getBody().writeTo(buffer);
LOGGER.debug("getBody: " + buffer.readUtf8());

//in the output i see
"author":{"name":"Author","iconUrl":"https://example.com/png.png","url":"https://example.com"}

I believe that's what's sent to discord. it should be "icon_url", and so the icon isn't visible on my embed as a result.
Maybe a json library conflict?

I think your issue is that you have a severely outdated version of the org.json dependency. This library needs at least 20190722 which added JSONPropertyName.

Correct
