Optimize App Performance and Scalability Course: Write a Startup Callback Function Task 1 Not Working

There's only one way to create a startup function, and it walks you through it. My answer looks exactly like the solution, but according to the course the function does not exist. I am having the same issue with Create Helper Functions Task 2. It seems like creating private functions as instructed do not actually get recognized by the course. I have finished the rest of the course besides these two modules which are impossible to finish currently. Any help would be greatly appreciated.
