I opened an issue https://github.com/apache/openwhisk/issues/5146 to describe an issue we encountered with an enterprise client where web actions returning some non standard HTTP status codes fail.
I think we can widen the handling of the status codes in the web actions handler by first doing the int to code conversion from the action's statusCode to a known value (as is done now), trapping any exceptions that occur and then creating a custom status code on demand. Looking through the akka library, I don't readily see a query method (to check if the int to code conversion will pass) but will look through the library a bit more. Any objections to this enhancement? -r
