Description

Can't upload image by using

var msg = {
   attachment: fs.createReadStream(__dirname + '/kitty.jpg')
};

localAPI.sendMessage(msg, "0000000000", function callback(obj, other) {
});

Error message on

ERR! ERROR in sendMessage --> { error: 'JSON.parse error. Check the detail property on this error.', ERR! ERROR in sendMessage --> detail: [SyntaxError: Unexpected end of input], ERR! ERROR in sendMessage --> res: '' }

In sendMessage.js defaultFuncs .post("https://www.facebook.com/ajax/mercury/send_messages.php", ctx.jar, form) .then(utils.parseAndCheckLogin)

If I send message. It call utils.parseAndCheckLogin 1 time But when I upload an attachment. Error happen.

Thank you :D

Research direction
Examine sendMessage.js around line where utils.parseAndCheckLogin is called when an attachment is present. The error 'Unexpected end of input' suggests the response from Facebook's endpoint might be empty or malformed. Investigate if the request payload differs when attachment is included versus a plain text message. Debug the response before parsing to verify its structure. Consider adding error handling for empty responses.
