I am currently facing an error especially when I run my flask .. The erro description is "AttributeError: 'tuple' object has no attribute 'values'"
The error points at line 11, and 331 which is defined in the function def course_options.
The error is found on this definition"options = [ tuple(course.values()) for course in courses]"
What I have tried:
