Unconditionally calling a function from inside itself creates a "recursion loop", and each call adds some data to the system stack. The stack quickly expands to exceed the available space (or a pre-set limit) to cause that error.

The function call should be outside (after) the function itself for this exercise.

And also note that the instructions say to "pass the string "Ruby" as an argument".
