Correct. This actually came up at the Nova mid cycle in a side<br>
conversation with Ironic and Neutron folks.<br>
<br>
HTTP error codes are not sufficiently granular to describe what happens<br>
when a REST service goes wrong, especially if it goes wrong in a way<br>
that would let the client do something other than blindly try the same<br>
request, or fail.<br>
<br>
Having a standard json error payload would be really nice.<br>
<br>
{<br>
fault: ComputeFeatureUnsupportedOnIns<u></u>tanceType,<br>
messsage: "This compute feature is not supported on this kind of<br>
instance type. If you need this feature please use a different instance<br>
type. See your cloud provider for options."<br>
}<br>
<br>
That would let us surface more specific errors.<br>

Standardization here from the API WG would be really great.<br>

<br>
</span>What about having a separate HTTP header that indicates the "OpenStack Error Code", along with a generated URI for finding more information about the error?<br>
<br>
Something like:<br>
<br>
X-OpenStack-Error-Code: 1234<br>
X-OpenStack-Error-Help-URI: <a href="http://errors.openstack.org/1234" target="_blank">
http://errors.openstack.org/<u></u>1234</a><br>
<br>
That way is completely backwards compatible (since we wouldn't be changing response payloads) and we could handle i18n entirely via the HTTP help service running on
<a href="http://errors.openstack.org/" target="_blank">errors.openstack.org</a>.<br>
<br>
Best,<br>
