Unclear error message for echo command

[trash-bin99]

Steps to reproduce: 1) add contacts until there are 10 in the list 2) create a folder using the command mkdir test 2) run the command 'echo 1 2 3 4 5 11 >> test'

Expected: Error message stating which contact is invalid

Actual: Vague message stating that a person does not exist in UNion

The error message should be more clear in identifying the cause of the error.
