Summary: When I tried to log in, the program had crashed when reading login.config. Steps to Reproduce: Step 1: Type the "login" command Step 2: Press Enter key to log in Actual Results: The program crashed with a list of errors. Expected Results: The program should run successfully and allow me to perform the login function.
The problem has been located. It seems like it is because of the different file encoding between login.config which is ascii and course data cache (json) which is utf-8.
The problem has been solved.
