rabbah opened a new pull request #3344: Extract message from callback and add it to pretty printed text.
URL: https://github.com/apache/incubator-openwhisk/pull/3344
 
 
   Here is a sample output:
   
   ```

   Failed to validate the SSL certificate for github.com:443. Make sure your
   managed systems have a valid CA certificate installed. You can use
   validate_certs=False if you do not need to confirm the servers identity but this
   is unsafe and not recommended. Paths checked for this platform: /etc/ssl/certs,

   ```
   
   The last paragraph is a result of this PR and I think easier to read.
