I do not expect it to return a nullptr in most cases. There could be a few corner cases that I am not aware of where it might.

I think we can change it to cast instead of dyn_cast, or if that doesn't work, we should error out if we get a nullptr, until we find a valid testcase where nullptr is expected. I am busy for the next couple days so I will work on this after sometime, but meanwhile if this change turns any buildbots green and is required sooner, I will be able to review the change if required. Thank you for pointing this issue out.
