Nullpointer Exception occurs when creating jcloud template for a given image

[Amani Soysa]

Hi

I am getting the following exception when creating jcloud template on top of devstack (folsom).

 Please note that I have given my image id as nova/61886474-123d-4c4a-8f68-9a5606bf76c0 and instanceType as nova/1. And I have uploaded this image in devstack sucessfully and was able to launch the instances. Also note the devstack default region is "RegionOne" and I have not changed it.

Appreciate if someone can give some tips on isolating this issue inorder to fix it.


Thanks & Regards

Hi Everett,

Thanks for looking at this issue and for  the quick response .. I have attached my code block [1] herewith. When I invoke build method in org.jclouds.compute.domain.internal.TemplateBuilderImpl (TemplateBuilderImpl.java:653)

Thanks,
Amani

Looking at your stack trace I see that the root cause of the NPE is that your Role id is null.

In the latest code the id field is Nullable [1] so I imagine you're at least a few versions back.

You'll also want to check that a role id is being returned when you authenticate to OpenStack. Have a look at Example 3.6 in [2].

Hope this helps,

Everett

Hi Everett,

Thanks for your response. Yes we are using an old version of jclouds (1.5.0-beta.5).  We found a workaround for this issue by making role id Nullable because we cannot afford to upgrade jclouds at the moment.

Thanks again for looking into this issue

Regards
