ChatGPT proposed code, refering to function in this library, which does not exist

[369Martin369]

Hi, Code ChatGPT suggested:

String generateQRCode(const String& data) {
QRCode qrcode;
uint8_t qrcodeData[qrcode_getBufferSize(3)];
qrcode_initText(&qrcode, qrcodeData, 3, 0, data.c_str());

String qrCodeHtml = "<img src="data:image/png;base64,";
qrCodeHtml += qrcode_getQRCode(&qrcode);
qrCodeHtml += "">";

return qrCodeHtml;
}

But..."qrcode_getQRCode" is not declared in qrcode.h!:
How comes that ChatGPT thinks this is part of Richard Moore's library??

CharGPT will often hallucinate. You cannot take its suggestions at face value and will often have to do additional research beyond code it proposes.

(my low-level libraries tend to be exclusively C, so if you see C++ syntax it is likely a hallucination)
