The pagination setting of the Blog plugin in mkdocs does not work

[shenweiyan]

My mkdocs.yml for blog setting:

- blog:
      blog_dir: blog
      post_dir: "{blog}/posts"
      archive: false
      categories: false
      pagination: true
      pagination_per_page: 5

When I execute the command mkdocs serve, I encounter the following error. Can anyone help me take a look and suggest a solution?

ERROR   -  Error reading page 'blog/page/2/index.md': Cmd('git') failed due to: exit code(128)

It looks like git is involved in this. Are you suggesting this is a bad interaction between the pagination and the revision date plugin? Any chance you could try to create a minimal reproduction for this?
