Lesson 6: Error in publish_source

[W-Tingyue]

When I tried to set publish_source according to the course content, the following error occurred. After repeatedly checking, I confirmed that my API Key is correct, and I have also configured the environment variables as instructed in the course. The deployment was successful, but when I set publish_source to True in the code, the following error always appears. Can anyone help me? Thanks in advance!
