POST /api/0.1/people 500 618ms

I am using meanstack. I have the following use statements in my express.js

//Set Request Size Limit
app.use(express.limit(100000000));

Within fiddler I can see the content-length header with a value of: 1078702

I believe this is in octets, this is 1.0787 megabytes.

I have no idea why express is not letting me post the json array I was posting previously in another express project that was not using the mean stack project structure.

Answer 1

If someone tried all the answers, but hadn't had any success yet and uses NGINX to host the site add this line to /etc/nginx/sites-available

client_max_body_size 100M; #100mb

Answer 2

I don't think this is the express global size limit, but specifically the connect.json middleware limit. This is 100kb by default when you use express.bodyParser() and don't provide a limit option.

Try:

app.post('/api/0.1/people', express.bodyParser({limit: '5mb'}), yourHandler);

Answer 3

A slightly different approach - the payload is too BIG

All the helpful answers so far deal with increasing the payload limit. But it might also be the case that the payload is indeed too big but for no good reason. If there's no valid reason for it to be, consider looking into why it's so bloated in the first place.

Our own experience

For example, in our case, an Angular app was greedily sending an entire object in the payload. When one bloated and redundant property was removed, the payload size was reduced by a factor of a 100. This significantly improved performance and resolved the 413 error.

Answer 4

In my case removing Content-type from the request headers worked.

Answer 5

The following worked for me... Just use

app.use(bodyParser({limit: '50mb'}));

that's it.

Tried all above and none worked. Found that even though we use like the following,

app.use(bodyParser());
app.use(bodyParser({limit: '50mb'}));
app.use(bodyParser.urlencoded({limit: '50mb'}));

only the 1st app.use(bodyParser()); one gets defined and the latter two lines were ignored.

Answer 6

I too faced that issue, I was making a silly mistake by repeating the app.use(bodyParser.json()) like below:

app.use(bodyParser.json())
app.use(bodyParser.json({ limit: '50mb' }))

by removing app.use(bodyParser.json()), solved the problem.
