Robocorp Lab (4.7.6)

JupyterLab v3 update

Upgrading to JupyterLab v3 enables us to avoid building JupyterLab extensions on your machine and deliver them in a more controlled manner. This reduces initial startup times and adds stability to the initialization phase. We are jumping in as early as we can as the release candidate is about to go live and the benefits were so great.

One of the most visible updates is that the Command Palette can now be trigged with: Ctrl/Cmd + Shift + C and works much like the command palette in VS Code.

Introducing Robocorp robots Portal

The Download Examples functionality in Robocorp Lab now points to our Portal site where you can discover shared robots and choose what you want to look into. Use the Open with Robocorp Lab button on each robot page to trigger robot retrieval to your machine. You can also just Download zip to get the robot source files.


  • Lab now has a direct method to fix the Windows Long Path support.
  • Fixes to the weird behavior for users that have spaces in their usernames:
    • Issues with UI locators Start browser timing out with Chrome.
    • Miniconda and Chromedriver workarounds improved.
  • Lab is now able to cancel running RCC tasks if the user opens and closes robots quickly.
  • Lab now shows RCC idle/busy state in the top-bar to signal environment setups etc.

Known issues

  • Execution does not always start when using Restart Kernel and Run All Cells... (all cells display [*]).
    • Cell-by-cell and Robot Run can be used as a workaround.
    • Running Restart Kernel and Run All Cells separately can be used as a workaround.
    • Affects macOS "Big Sur", but also some Windows installations.
    • The underlying JupyterLab issue #9008 is being fixed.
  • JupyterLab V3 has a new Single-document mode that activates automatically if you resize the editor window to a small enough size.
    • To get back to normal mode go to: View -> Click on Single-Document Mode to deactivate it.
    • We are looking into ways of disabling this as it really serves little purpose in automation cases.
