dubee opened a new issue #4028: Uncaught exception in invoker URL: https://github.com/apache/incubator-openwhisk/issues/4028 Below is an uncaught exception that I believe occurs when an action's response exceeds the configured HTTP max content-length. We should catch this exception properly. ``` configure this by setting `akka.http.[server|client].parsing.max-content-length` or calling `HttpEntity.withSizeLimit` before materializing the dataBytes stream. akka.http.scaladsl.model.EntityStreamSizeException: EntityStreamSizeException: actual entity size (Some(27711372)) exceeded content length limit (8388608 bytes)!
