I just ran into this as well. Not sure what the cause is.

[RyanCavanaugh]

Root cause isn't clear, any one of our code action providers might be incorrectly returning an undefined element of the array. Adding filtering code that will tell us what the diagnostic code is so we can stop crashing + figure out which provider as fault.

My kingdom for --strictNullChecks in the compiler codebase
