In my web application, photos are sent to an azure container. The problem is that randomly many images fall into the container with a size of 0 bytes, therefore unusable. I have reviewed the azure linux server and I have noticed that the web application always sends the photos well. Because I keep them temporarily and keep them with the correct sizes. The problem is when I send them, which sends some with 0 bytes.
The system sends the photos correctly when I test it locally or when I try it on other platforms like heroku. I do not understand why only in Azure causes this problem.
This is my code, but I repeat, locally and in other platforms it works well even using the azure container. I think it's configuration of the web app within azure. But I do not know.
let almacenamiento = multer.diskStorage({
destination: function (req, file, cb) {
cb(null, 'uploads')
},
filename: function (req, file, cb) {
cb(null,Date.now() + '-' + file.originalname);
}
});
let upload = multer({ storage: almacenamiento,
fileFilter: function (req, file, cb) {
let ext = path.extname(file.originalname);
console.log(ext);
const regex = /(\.JPEG|\.jpeg|\.png|\.PNG|\.jpg|\.JPG)+/g;
if (!ext.match(regex)) {
return cb(new Error('El archivo debe ser una imagen!'))
}
cb(null, true)
},
limits: { fileSize: 5*1024*1024 }
});
