This is my workflow.yml file.
There's an error when pulling in blog posts.
I am using 'Tistory', a widely used blog site in South Korea.
I've entered the correct RSS page in the feed list, but it doesn't work. It used to work, but it hasn't been functioning for the past two weeks.
Can you help me figure out what's wrong?
