Response reason phrase exceeds the configured limit of 64 characters

[Tim Pigden]

Hi - I get the following. Not sure how to find out what the response was or how to change the configuration. Any help much appreciated as I'm now stuck.

akka.http.model.IllegalResponseException: Response reason phrase exceeds the configured limit of 64 characters
   at akka.http.engine.client.HttpClient$$anonfun$2.applyOrElse(HttpClient.scala:89) ~[akka-http-core-experimental_2.11-1.0-M3.jar:1.0-M3]
   at akka.http.engine.client.HttpClient$$anonfun$2.applyOrElse(HttpClient.scala:86) ~[akka-http-core-experimental_2.11-1.0-M3.jar:1.0-M3]

to answer myself, config (note you need to use "client" to override it)

akka.http.client.parsing {
  max-response-reason-length = 512
}

Tim,

You can find more about this from this thread: https://groups.google.com/forum/#!topic/spray-user/CF2rsUKNvwQ and this stack overflow questiON: http://stackoverflow.com/questions/9513447/http-response-status-line-maximum-size

While setting the value higher will undoubtedly fix the problem, you have to ask yourself why your server is sending back such large response reason phrases when the standard shows a limit of 31 characters for these. What's the reason phrase you are getting?

Reid.

Hi - it's a reasonable question. I found Mathias's comment.

What I'm getting back is the full path name of the missing resource. And since I'm nesting resources and using 64-bit uuids in resource names this is way over 64 characters.

I'm using the exist xml database but I have no (easy) way to control it's responses. Of course if I don't ask for what's not there, the problem doesn't manifest itself and theoretically i know what is there but "somebody else" might have deleted it.

From my reading of the second post, the 31 characters is not a defined standard, merely the largest standard message, and no defined maximum. 

Since the eXist database is only serving my application on a local net my easiest solution is just to up the count.
