Only comparing the build cache key on its own does not give much information, so we need to look at some finer grained data to be able to diagnose the cache miss.
A list of all inputs to the computed build cache key can be found in the <<build_cache.adoc#sec:task_output_caching_details,section on cacheable tasks>>.

	ErrStatus metav1.Status
