Finatra TooLongMessageException HTTP content length exceeded 5242880 bytes, despite flag setting more bytes

Question

I'm seeing a TooLongMessageException HTTP content length exceeded 5242880 bytes. exception thrown from my finatra server. Looking at the flags available via -help=true, it looks like the flag to set is maxRequestSize. Here is the output of the help command

flags:
  -admin.announce='java.lang.String': Address for announcing admin server
  -admin.port=':9990': Admin http server port
  -cert.path='': path to SSL certificate
  -doc.root='': File serving directory/namespace for classpath resources
  -help='false': Show this help
  -http.announce='java.lang.String': Address for announcing HTTP server
  -http.name='http': Http server name

I've passed in -maxRequestSize=10.megabytes and can see the value in the /admin/registry.json document: maxRequestSize: "10485760.bytes" but I'm still seeing the TooLongMessageException with the 5 megabyte value. How do I increase this max size?

Answer 1

Maybe in code it is being overwritten?

You could do it programmatically

> override def configureHttpServer(server: Http.Server): Http.Server = {
>     server.withAdmissionControl.concurrencyLimit(maxConcurrentRequests = 2000, maxWaiters = 0)
>       .withResponseClassifier(HttpResponseClassifier.ServerErrorsAsFailures)
>       .withMaxRequestSize(StorageUnit.fromMegabytes(200))
>       .withRequestTimeout(50.seconds)   }
