Error: Project details could not be queried.

[LuckyJinging]

I can obtain the project list with ols list, but I got an error when I do ols -l or ols -r to sync files.

Project queried successfully. ✅ Querying project 💥 Querying project details Error: Project details could not be queried.

Same problem here, I could not download the project files

Same here, more info:

> ols -v -n 'PROJECT' -r
Project queried successfully.

💥  Querying project details
Error: Project details could not be queried.

That line reads:

    164         # Convert cookie from CookieJar to string
    165         cookie = "GCLB={}; overleaf_session2={}" \
    166             .format(
    167             self._cookie["GCLB"],
    168             self._cookie["overleaf_session2"]
    169         )

That self._cookie would probably need to come from OverleafClient.login() which states, that its DEPRECATED. I hope that helps a bit.

Same issue, itstorque's commit remedied this after generating a new login cookie

[CeciliaCoelho]

After getting the same error itstorque's commit fixed it but today a different error message appeared. Using linux

 >> ols login 
Persisted Overleaf cookie already exist. Do you want to override it? [y/N]: y
⠸ Loginjs: Uncaught TypeError: Cannot read properties of undefined (reading 'href')
js: Uncaught TypeError: Cannot read properties of undefined (reading 'content')
Login successful. Cookie persisted as `.olauth`. You may now sync your project.
✅  Login

>> ols -r

Hi @CeciliaCoelho, @itstorque's commit also stopped working for me. It seems Overleaf has made some changes on the website. These modifications (see #66) worked for me.

[itstorque]

Took a look at the rendered HTML for the landing page, they removed the classes for the links in the table. I think replacing the line

JAVASCRIPT_EXTRACT_PROJECT_URL = "document.getElementsByClassName('project-list-table-name-link')[0].href"

with this

JAVASCRIPT_EXTRACT_PROJECT_URL = "document.getElementsByTagName('tbody')[0].children[0].getElementsByTagName('a')[0].href"

should work. Its very jank, if they introduce another table in the HTML before the project list, it will break.

Another possible implementation that I prefer would be replacing that line with

JAVASCRIPT_EXTRACT_PROJECT_URL = "q=0;for (const c of document.getElementsByTagName('a')) { if(c.href.indexOf('/project/') > 0) { q=c.href; break; } }; q"

The thinking here is that support for URLs is more concrete (backcompatibility) and therefore changes to the html page wouldn't break the ability to find a link to a project to load the GCLB cookie.

Note: I didn't test these, but I am confident that they should work (lmk otherwise)

[svennniiii]

I think this alone doesn't do the trick. Additionally, I had to do two changes in class OverleafClient(object) in the methods that deal with querying the project (def all_projects(self) and def get_project(self)). (see #66)

I don't know how the old landing page looked like, but it may be due to the same design changes.

~~I replaced the files in the pip module with the fixes from the linked repository in #66, but I am getting the following issue using ols download -v (with a fresh login token)~~

💥  Downloading project's PDF
Error: Downloading project's PDF failed. Please try again.

EDIT:

User error, I forgot to select the project I want to sync / download.

correct command to do is: ols download -n my_project the fix works perfectly!
