Fixes #14368
Motivation
Using
{{workflow.failures}}
within an exit handler in a resource template (workflow of workflows) caused a validation error. The changes allow to use{{workflow.failures}}
in this context.Modifications
For template validation, if the template contains a resource manifest,
{{workflow.failures}}
is replaced by a temporary placeholder to allow validation to pass. The strategy mirrors what already happens, e.g., when a exit hook is detected in the template.Verification
Unit test was added. Test workflow from #14368 can now run without problems.
Documentation
Bugfix. Existing documentation suggests that
{{workflow.failures}}
should work in all contexts where exit handlers are used, including from within a workflow of workflows
