@g-saracca Where are the functional tests for this PR?

[g-saracca]

@ofahimIQSS Oh, I didn't think it was necessary to validate the isPartOf field in a functional test since it was already being tested through an integration test, that's why there are none.

As discussed in the Front-end standup, did visual inspection of the code, no issues observed. Additional ticket to be opened to track adding of integration tests for this ticket.
