Nodejs CORS not working on some express routes,












1















I am using 'cors' module to enable CORS on my EXPRESS APP, but its not Working on two of my routes, I am deploying on google app engine, uploading files on google cloud storage.



app.post('/image',cors(corsOptions), authenticateVerifiedadmin, multer.single('file'), (req, res, next) => {
res.header("Access-Control-Allow-Origin", "*");
if (!req.file) {
res.status(400).send('No file uploaded.');
return;
}
var eventID = _.pick(req.body, ['eventID']);
const gcsname = eventID.eventID + req.file.originalname;
const blob = bucket.file(gcsname);
const blobStream = blob.createWriteStream({
resumable: false
});
blobStream.on('error', (err) => {
next(err);
});
blobStream.on('finish', () => {
var cloudStorageObject = gcsname;
file.makePublic().then(() => {
var cloudStoragePublicUrl = getPublicUrl(gcsname);

Event.findOne({
_id: eventID.eventID
}).then(event => {
debugger;
event.images.push({
imageurl: cloudStoragePublicUrl
})
return event.save().then(() => {
res.status(200).send()

}).catch((e) => {
res.status(400).send()

})
})
});

//debugger;
// console.log(req.files)


})
})


I get 502 status code every time, other routes are working fine.
missing something???

  • 502 is Bad Gateway so your problem is not related to CORS
