CommandError: An error occurred during rendering

[Eric K]

Repeatedly seeing the following error during devstack setup in tempest tests in Congress (for example: http://logs.openstack.org/57/356157/4/check/gate-congress-dsvm-api/70474ca/logs/devstack-early.txt.gz [also attached]). Any idea whether it's a horizon bug or devstack bug or user error on Congress side? Thanks so much!

Lowering priority in Congress because work-around in place.

'<link href='{{ STATIC_URL }}horizon/lib/jquery-ui/ui/jquery-ui.css' type='text/css' media='screen' rel='stylesheet' />'

should be

'<link href='{{ STATIC_URL }}horizon/lib/jquery-ui/jquery-ui.css' type='text/css' media='screen' rel='stylesheet' />'

This is because legacy versions had the 'ui/' directory, but later versions dropped it. We actually have a workaround in Horizon for this at https://github.com/openstack/horizon/blob/348069364cf217217af6436e455ee04587bfd26b/openstack_dashboard/utils/settings.py#L243

My advice would just be to add the original compress line back to your template, and drop the 'ui/' part. You can see where the files are by pulling Horizon, running 'python manage.py collectstatic' and viewing the 'static/' dir in your horizon root.
