Timeline slider not shown when base_url is set #393

OLD Description

When Jupyter Lab is started as as single-user server in Jupyter Hub, the document timeline widget uses an incorrect url, which can be seen from the browser console when clicking on the timeline icon:

Screenshot 2024-11-01 at 22 23 53

As can be seen from this screenshot, the url has the part /collaboration/timeline two times.

If I manually change the url by removing one duplicate and open it in a browser, it appears to be working fine:

{"roomId": "json:notebook:1acd8c55-cfea-4e70-aa54-f7ad73df5511", "timestamps": [1730491695.928937], "forkRoom": "426ef1f297924abfb3af89c85f1ccf82", "sessionId": "cff41fa8-722f-4dc2-b52b-07db54815389"}

Reproduce

  1. Install the required packages in a fresh python environment: conda install -c conda-forge jupyterhub jupyterlab jupyter-collaboration
  2. Start jupyterhub: jupyterhub --JupyterHub.authenticator_class='dummy' --JupyterHub.spawner_class='simple'
  3. Open the url http://localhost:8000 and enter any user name, e.g., bob
  4. Open a new notebook
  5. Open the browser console and click on the timeline icon
  6. Observe the above error message in the console

Expected behavior

A slider should appear next to the timeline icon.

ykazakov commented 2 weeks ago

Actually, exactly the same problem takes place even without jupyterhub if one changes the default base_url (which jupyterhub does):

jupyter lab --ServerApp.base_url='/user/bob'
ykazakov commented 2 weeks ago

Updated report

Description

When Jupyter Lab starts with a custom base_url, the document timeline widget uses an incorrect url, which can be seen from the browser console when clicking on the timeline icon:

Screenshot 2024-11-07 at 16 05 34

As can be seen from this screenshot, the url has the fragment /collaboration/timeline two times.

If I manually change the url by removing one duplicate and open it in a browser, it appears to be working fine:

{"roomId": "json:notebook:6ac6ac6d-7495-48cc-a50b-079b716639b6", "timestamps": [1730991797.4978712, 1730991823.8297029, 1730991841.182337], "forkRoom": "dcbf793c2a554d11bcb811537ed539e8", "sessionId": "48f278d7-0dd0-4617-b81e-bc3a6198e682"}

Reproduce

  1. Install the required packages in a fresh python environment: conda install -c conda-forge jupyterlab jupyter-collaboration
  2. Start jupyterlab: jupyter lab --ServerApp.base_url='/user/bob'
  3. Open a new notebook
  4. Open the browser console and click on the timeline icon
  5. Observe the above error message in the console

Expected behavior

A slider should appear next to the timeline icon.
