Unable to launch Sahara cluster;'Error type says 'None type iterable'

[Soumitri Vadali]

I can create node templates and other cluster templates;however when i try to launch cluster from the cluster template, it never works. the cluster will be spawning and then it will say there is a nonetype iterable error. Most troublesome part is that I could not find any log files for Sahara dashboard or sahara. I installed on top of devstack.

Can you provide at least event log data?

It's located at cluster details page, event log tab

[Soumitri Vadali (soumitriv93)]

Hello, sure. thanks for swift reply. I have attached log details in the photos. Basically it fails at the very first step of creating a heat stack.

have attached another screenshot of the failed events details here.

Ok, then I will need information about created stacks.

Could you please execute heat stack-list --show-hidden to show all stacks which was created?

also, please provide cluster template and node group templates included in that cluster template at least.

[Vitalii Gridnev (vgridnev)]

to find logs, probably you can execute

find / -name "sahara*" 2>/dev/null . Is there something?

[Vitalii Gridnev (vgridnev)]

So, i guess that I know reason of issue. Probably you have not used auto-security groups?
