Hi
i am having some issue adding a new device D35 to greengrass .
The first time the role is run on devices newly added to {{ api_greengrass_group_thing_list }} the playbook will fail at this point but then running the playbook a second time the error will go away.

TASK [aws.greengrass : Template out device config] *************************************************************************
fatal: [zzz-ops-greengrass-1]: FAILED! => {“changed”: false, “msg”: “AnsibleUndefinedVariable: ‘dict object’ has no attribute u’D35_cert_arn’”}
[WARNING]: Failure using method (v2_runner_on_failed) in callback plugin (<ansible.plugins.callback.mail.CallbackModule
object at 0x7f2a1bdfda50>): [Errno 111] Connection refused

Need some hints what could me the issue.
