If you add the package that @juliancwirko suggests, you don’t need to register the helper. I had this same problem because I had registered the helper earlier, forgot about it, and then tried adding the package and using it. Make sure to remove that helper.
I fixed it, phew! I had to remove the helper declaration and use the #markdown + /markdown tags. The plural sight course is slightly out of date I guess… thanks for pointing me in the right direction
