Command ols list doesn't work. I am successfully logged in via ols login. This is the output of ols list -v:

Hey, I came across this. I'd point out the Overleaf team introduced some changes last year, which may cause this issue. Since I'm an overleaf/overleaf-sync newbie, I'd appreciate experts' help! :heart:

The Overleaf team has been working on a migration project for the last year and completed it.

Before

• meta name: ol-projects
• json structure

  // consists of a project array
  [
    {"id": "...", "name": "..."},
    {"id": "...", "name": "..."},
    // ...
  ]
  

After

• meta name: ol-prefetchedProjectsBlob
• json structure

  // became a children of an object
  {
    "totalSize": 5,
    "projects": [
      { "id": "...", "name": "..." },
      { "id": "...", "name": "..." },
     // ...
    ]
  }
  

Git history

Gathered by me after digging the git history of overleaf/overleaf repository and may be incorrect.

Take a look at the commits that introduced these changes into Overleaf (CE edition).

• into controller: https://github.com/overleaf/overleaf/commit/a0fabee3b4342204eb83bd68ffa195491c1faff7 on Sep 14, 2022
• into view: https://github.com/overleaf/overleaf/commit/cdbf8c1831fe7468e52e8376031811d04c5e6555 on Oct 13, 2022

Two versions of the project list page seem to have been maintained during migration, and the old one that contains ol-project meta was removed at the commit https://github.com/overleaf/overleaf/commit/3e315eada1a99bdd6eee7db48b278118f69ced99 on May 26, 2023. I mentioned the removal of services/web/app/views/project/list.pug.

What can we do?

One patch will be to have OverleafClient.filter_projects() accept new structure dict and rename ol-projects ol-prefetchedProjectsBlob in each caller. https://github.com/moritzgloeckl/overleaf-sync/blob/aa62165eb9eba48f8b8bf3d93358f9feed0bf5a9/olsync/olclient.py#L38-L41 to

    @staticmethod
    def filter_projects(json_content, more_attrs=None):
        more_attrs = more_attrs or {}
+        projects = json_content.get("projects", []) # you have to check json_content is not None
-        for p in json_content:
+        for p in projects:

and https://github.com/moritzgloeckl/overleaf-sync/blob/aa62165eb9eba48f8b8bf3d93358f9feed0bf5a9/olsync/olclient.py#L91-L93 to

        json_content = json.loads(
-            BeautifulSoup(projects_page.content, 'html.parser').find('meta', {'name': 'ol-projects'}).get('content'))
+            BeautifulSoup(projects_page.content, 'html.parser').find('meta', {'name': 'ol-prefetchedProjectsBlob'}).get('content'))
        return list(OverleafClient.filter_projects(json_content))

My suggestion seems not intuitive because to call filter_project with an object does not follow the standard. In other words, python's built-in filter takes an array. So return list(OverleafClient.filter_projects(json_content).get("projects")) should be better. Anyone has an idea? Thanks.

Hi sorry, I did not understand how I can fix this error. Again I am sorry as I am a noob on git.

I think you have to use this repo: https://github.com/svennniiii/overleaf-sync Just clone the project wherever you want git clone https://github.com/svennniiii/overleaf-sync and run pip install . inside the folder. This should install the script.
