Error fetching bookmarks: Error: HTTP error! status: 400

[Ashutosh-Sharma-IN]

hi - i am trying to use the extension on Chrome. Logged in to X. Downloaded the code from Github, installed the extension.
Open and process the steps as mentioned. When I click on the extension, it opens a small window with title Twitter Bookmarks Explorer and a blue button titled Export Bookmarks.
When I click on this button, it opens a new X window but does nothing. When I check on errors in the extension page, here is what I see:

Error fetching bookmarks: Error: HTTP error! status: 400
}
});
}
} catch (error) {
console.error("Error fetching bookmarks:", error);

    }
  });
}
