akrabat opened a new issue #3321: __ow_body should always be a string (or null?)
URL: https://github.com/apache/incubator-openwhisk/issues/3321
 
 
   Given an action created with the `--web raw` parameter, a request with no body results in `__ow_body` being set to an empty array, otherwise it's a string.
   
   This is a nuisance as it changes type. I think that it should either be an empty string or null for this situation.
