Open edx ios App: When Entering the course ,could not see the course content, but prompt “Your action could not be completed” .
Server is K version,ios app source is clone from GitHub - edx/edx-app-ios: The Open EdX mobile app for iOS! ,version is 2.24.1,
the log fragment of client is
“[ERROR|Network Authenticator] @ NetworkManager+Authenticators.swift:67 - Request failed: Optional(<NSHTTPURLResponse: 0x280438e40> { URL: https://abc.tuxrman.com/api/courses/blocks/blocks/?block_counts=video&course_id=course-v1%3Aedxgroup%2Bedx01%2B2020_T2&depth=all&nav_depth=3&requested_fields=graded%2Cstudent_view_multi_device%2Cformat%2Cdue&student_view_data=video%2Cdiscussion&username=zsj }”.

My question is what’s wrong here? And how to do?

Hi bro, I faced with this issue and resolved. I think you need config API_URL_VERSION for BLOCKS:
Example: API_URL_VERSION:
BLOCKS: “v1”.
