So this flakiness is caused by one of the function in the FTR. This function has the chance to return undefined (it does this randomly, I can only reproduce this on Flaky Test Runner and not locally),
an easy way to go around this is by using mock benchmark rules instead of getting the fetching the benchmark rules from saved object (which can fail)

@animehart can you provide more context on what is the function you are talking about, how it was discovered that it can return undefined randomly?
