Error: EROFS: read-only file system, open "Filename" when uploading an image to Cyclic.sh

I am trying to first upload my image "formData" to the backend, then use the image path to upload it to ImageBB.

var storage = multer.diskStorage({
    destination: function (req, file, cb) {
      cb(null, './tmp')
    },
    filename: function (req, file, cb) {
      cb(null, file.originalname)
    }
})

var upload = multer({ storage: storage })

app.use(express.static(__dirname + '/tmp'));
app.use('./tmp', express.static('tmp'));

app.post(
//Uploading to ImageBB
);

This seems to work fine in my localhost, BUT when I deployed it on Cyclic.sh , this error appears in the logs: Error: EROFS: read-only file system, open "Filename"

Solution

  • I think it's solved.
    Though all I did was changing the ./tmp to /tmp.
