Invalid/wrong data in A&AI is throwing an error. Ideally we need not fix it but due to wrong data in integration test environment we are encountering this and it is better we defensively handle the data error caused by wrong data in A&AI such as the one below. The vserver was missing cloud-owner information in one of the test data and it was throwing an error like below. If this case occur we discard the candidate and continue with the set of candidates with valid data.
