NodeJS write base64 encoded image to file
Got same bug, it's because of incorrect url path, You may added app.use("/", express.static(path.join(__dirname, 'public')));, so no need to add the public in the url, check your url path once.
working sample :
url = req.protocol+'://'+req.headers.host+"/"+filename;url = req.protocol+'://'+req.headers.host+"/images/"+filename;// its inpublic/images
Try using ./public/aboutToGiveUp.png or make sure that the path is relative to the file containing this code.
