DCAE health check fails, but closed loop works so far - not sure it is an inconsistency between  1.1.0 DCAE images in an otherwise 1.0.0 docker environment. I checked CDAP to receive messages from vFW as a "health check"

Basic DCAE Health Check                                               | FAIL |
Resolving variable '${resp.json()}' failed: JSONDecodeError: Expecting value: line 1 column 1 (char 0)

as the message below suggests

 MANAGEMENT-SERVER-WEB-REQUEST-UNKNOWN-EXCEPTION-4012E type=Unable to translate between versions: ONAP-R2

To me it seems as if the script does not honor the content type and tries to JSON-decode the error document.

This is an outcome of https://jira.onap.org/browse/DCAEGEN2-69  see last two comments there

(20170907) Rackspace - still see parts of this HC failure in DCAE - including the ONAP-R2 log
