.createServerImage() errors with "Invalid format (output) missing from remote call"

[vladfulgeanu]

When issuing a .createServerImage() command, the response returns the following error in the callback:

{ Error: Invalid format (output) missing from remote call
    at _getRequestError (/home/test/node_modules/openstack-wrapper/lib/os-request.js:219:20)

  code: 'REMOTEERROR',
  detail: 
   { remoteMethod: 'POST',
     remoteURI: '~~~remoteURI~~~',
     remoteStatusCode: 202,
     remoteMessage: '',
     remoteCode: '',
     remoteDetail: '',
     responseTime: 0.975 } }

The issued command looks something like this:

    await  nova.createServerImage(serverId, {
        "name" :   `image ${dateformat(new Date(), "dd/mm/yyyy HH:MM")}`,
        "metadata": {
            "test_var": "test_val"
        }
    }, (error, result) => {
        if (error) {
            console.log(error); // will output the earlier error
        }
        console.log(result);  // will be undefined
    });

even though the image is created fine, also seen by the remoteStatusCode 202.

I want to know if this is a problem with the cloud provider (OVH) because there is no body in their response.

Sorry for the slow response here - your provider (OVH) is probably doing this the right way. Nova has simply changed the output format recently and the library wasn't supporting the older format.

Just published a new version (2.2.0) that should support both new and old formats on that call and should fix your issue.
