Hi.
I believe that the issue in question is known to us.
The 16.2 RHOSP no longer generates usable inventory for validations, so the user has to supply it manually.[0]
More general fix is in development that should hopefully eliminate the issue entirely.

Comment 2 Jiri Podivin 2022-04-07 12:53:10 UTC

We have a workaround, proper fix is in progress. 

Customer needs to explicitly specify an ansible inventory with the '--inventory'.

For example: 
> openstack tripleo validator run --group pre-introspection --inventory ./path/to/inventory.yaml

If possible we should get it published as an article.
