If you input a Cohort ID that doesn't exist, there is no failure. It will simply return nothing for that Cohort. This is fine when you simply specify one cohort ID, as the failure will be caught downstream. However, if you specify multiple cohort ID's, and one is invalid, the failure will be silent.
