NodeJS Express Request Entity Too Large

Question

I've tried many solutions listed here (increasing of memory limit, adding parameterlimit, adding type as 'application/json') to fix this 'Request Entity too large' error (it also returns http code 413). But none of them seem to make this error go away.

The current size of the json can range from 200k up to 400k entities.

Here is the current configuration:

app.use( bodyParser.json({limit: "15360mb", type:'application/json'}) );      
app.use(bodyParser.urlencoded({
  limit: "15360mb",
  extended: true,
  parameterLimit:5000000,
  type:'application/json'
})); 
app.use(bodyParser())

Any ideas on how to increase the limit?

}

Solution

The error was indeed due to wrong configuration on elasticsearch and not nodejs. Manage to fix this by following https://github.com/elastic/elasticsearch-js/issues/241 and setting http.max_content_length: 500mb in elasticsearch.yml.

This issue has been fixed. Thanks for all the input!

If You doesn't solve your issue, bodyParser also has a limit. You must use

app.use(bodyParser({limit: '4MB'}))
