This is giving me flashbacks to a separate conversation I was having on the IE regarding required inputs. It is frustrating to me that I am clearly not on the same wavelength as NI here. I feel like required inputs should be relatively rare (and I think warnings are more appropriate). My frustration stems mainly from the fact that everyone has their own idea about where to draw the line.
Me: I think, if anything, the type input to bundle (probably Type Cast as well) should be required, it seems fragile to rely on implicit typing in that node. At the same time I can not figure out why the format string is required in Spreadsheet string to Array when I can create the default empty constant and it promptly gets ignored by the function and it then works fine.
NI: The type input to bundle is perfectly fine being optional, and by-gum you had better wire that format string.
Long story short: There is a bug, I would not call it serious, others are more than welcome to. My "fix" would be to make the type input on the bundle function required. Lucky for you, I do not get to decide those things.
