Hello
Apparently other people have the same issue and cannot use cron triggers anymore:
https://bugs.launchpad.net/mistral/+bug/1843175
We also tried with following patch installed but the same error persists:
https://opendev.org/openstack/mistral/commit/6102c5251e29c1efe73c92935a051feff0f649c7?style=split

Dear All
We are using Mistral 7.0.1.1 with Openstack Rocky. (with federated users)
We can create and execute a workflow via horizon, but cron triggers always fail with this error:
{
"result":
"The action raised an exception [
action_ex_id=ef878c48-d0ad-4564-9b7e-a06f07a70ded,

params='{
u'action_region': u'ch-zh1',
u'name': u'42724489-1912-44d1-9a59-6c7a4bebebfa'
}'
]
\n NovaAction.servers.find failed: You are not authorized to perform the requested action: identity:validate_token. (HTTP 403) (Request-ID: req-ec1aea36-c198-4307-bf01-58aca74fad33)
"
}
Adding the role admin or service to the user logged in horizon is "fixing" the issue, I mean that the cron trigger then works as expected,
but it would be obviously a bad idea to do this for all normal users ;-)
So my question: is it a config problem on our side ? is it a known bug? or is it a feature in the sense that cron triggers are for normal users?
After digging in the keystone debug logs (see at the end below), I found that RBAC check identity:validate_token an deny the authorization.
But according to the policy.json (in keystone and in horizon), rule:owner should be enough to grant it...:
"identity:validate_token": "rule:service_admin_or_owner",
"service_admin_or_owner": "rule:service_or_admin or rule:owner",
"service_or_admin": "rule:admin_required or rule:service_role",
"service_role": "role:service",
"owner": "user_id:%(user_id)s or user_id:%(target.token.user_id)s",
Thank you in advance for your help.
Best Regards
