Error: request entity too large

I already tried this option but still same error. Here is a sample code from index.js:

swaggerTools.initializeMiddleware(swaggerDoc, function (middleware) {
  // Interpret Swagger resources and attach metadata to request - must be first in swagger-tools middleware chain
     app.use(middleware.swaggerMetadata());
  /*app.use(middleware.swaggerMetadata(
      bodyParser.json({limit: "50mb"}),
      bodyParser.urlencoded({ limit: "50mb", extended: true })
  )
  );*/

  // Validate Swagger requests
  app.use(middleware.swaggerValidator());

  // Route validated requests to appropriate controller
  app.use(middleware.swaggerRouter(options));

  // Serve the Swagger documents and Swagger UI
  app.use(middleware.swaggerUi());

  //app.use(bodyParser.json({limit: "50mb"}));
  //app.use(bodyParser.urlencoded({ limit: "50mb", extended: true }));

  app.use(bodyParser.json({limit: 10 * 1024 * 1024}));
  app.use(bodyParser.raw({limit: 10 * 1024 * 1024}));
  app.use(bodyParser.text({limit: 10 * 1024 * 1024}));
  app.use(bodyParser.urlencoded({limit: 10 * 1024 * 1024, extended: true}));

Answer 1

According to instructions specified in https://github.com/apigee-127/swagger-tools/issues/248, you want to configure bodyParser before initializing swagger, like this:

app.use(bodyParser.json({limit: 10 * 1024 * 1024}));
app.use(bodyParser.raw({limit: 10 * 1024 * 1024}));

app.use(require("./router")); // in this sample, this is where you configure your Swagger middleware

This way, Swagger will use your configured bodyParser with the limits you set. I was solving the same problem and this solved it.
