No worry, I had actually forgotten about this. In a more recent version (2022.3.0), both 1D and 2D case return the same ValueError with a relatively clear message x and y arrays must have at least 2 entries.

I'm still proposing that any valid code with sel should behave the same with interp, and thus that interp should work when a dimension has a single entry. But this is a low priority issue with easy workarounds.
