Hello,

I have a route that regularly receives large POST requests. It is throwing the following exception sporadically: 

Exception Occurred: akka.http.scaladsl.model.EntityStreamException: Entity stream truncation

How do I address this? Is there a setting that I need to increase?

Thanks!

Hello,

Still having this issue. It occurs on seemingly random REST endpoints.

Can anyone provide insight?

I'm having the same problem. Doesn't seem limited to large requests. It does seem to be in Akka though, so maybe it's better if we ask over there?

Check out https://groups.google.com/d/msg/akka-user/gQM8N7O7jxg/RMxLsXq7AwAJ - looks like this happens if the client terminates the connection prior to sending the full request.

Sounds like a nuisance exception in the sense that this will just happen from time to time in the real world and there's not that much we can do about it.

Hi, I am also seeing this exception sometimes. I am using akka streaming framework and akka HTTP flow. Any ideas on what should be the Supervision Strategy for this exception?
Resume or Restart?
