Note that you are apparently using an ancient version of Julia (\< 1.5). If you upgrade to the latest version (1.6), then (a) your code will work fine in an interactive environment (e.g. the REPL) and (b) in a script it will give a clearer error message. (If you use Jupyter notebooks, then it will work in earlier versions too.)
