Comment 4 for bug 1624727

@michele - did you re-run openstack undercloud install after applying those patches?

That is required to reload the mistral actions/workflows from the patches touching tripleo-common, or you can do it manually like:

$ cat mistral_update.sh
#!/bin/bash
sudo mistral-db-manage populate
sleep 1
sudo systemctl restart openstack-mistral-engine
sudo systemctl restart openstack-mistral-executor
sudo systemctl restart openstack-mistral-api
sleep 1

for workbook in $(mistral workbook-list | grep tripleo | cut -f 2 -d ' '); do
    mistral workbook-delete $workbook
done
for workflow in $(mistral workflow-list | grep tripleo | cut -f 2 -d ' '); do
    mistral workflow-delete $workflow
done
for workbook in $(ls /usr/share/openstack-tripleo-common/workbooks/*); do
    mistral workbook-create $workbook
done
