Uncaught exception in invoker

[dubee]

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.

[ERROR] Error during preStart in [akka.http.scaladsl.model.HttpEntity$Limitable@21dd4c89]: EntityStreamSizeException: actual entity size (Some(27711372)) exceeded content length limit (8388608 bytes)! You can configure this by setting `akka.http.[server|client].parsing.max-content-length` or calling `HttpEntity.withSizeLimit` before materializing the dataBytes stream.

Do you know where this exception is thrown?

I see this error when I try to create a action code with size roughly ~ 8 MB.

Possibly this may be coming with switch to attachments and not seen when code is not stored as attachment

@tz70s in #3757 suggested to bump http.[client/server].parsing.max-content-length as also suggested by exception message
