Fix for missing null check in workflow list

@@ -127,9 +127,12 @@ In this examples there are two workflows:
 1. Messages your team every minute (!) and asks them how they're doing.
 2. Receives the interaction from users. It adds reactions when the buttons are pressed and posts a message when a user selects from the dropdown menu.
 
+Please note, that to use `jsx-slack` you will need to add the `jsxImportSource` pragma to the top of your file. This is because `jsx-slack` is not a React library, but it uses the same syntax as React. Also, you might need to add `"jsx": "react-jsx"` to your `compilerOption` in `tsconfig.json`. The workflow file needs to be a `.jsx` or `.tsx` file (like when you use React).
