SAS University Edition: Help Center

Why am I seeing an "Invalid response: 500 Internal Server Error" message when I create a Jupyter notebook?

When you create a notebook or open an existing notebook in JupyterLab, you might see this error:

Invalid response: 500 Internal Server Error.

This error can occur when you have restarted VirtualBox and JupyterLab after previously saving the machine state and closing your virtual machine.

To correct this problem, close the virtual machine in either of these ways:

  • In the VirtualBox window, select the SAS University Edition vApp, and then select Machine > Close > ACPI Shutdown.
  • In the Welcome window, select File > Close. In the Close Virtual Machine window, select Send the shutdown signal, and click OK.
Restart SAS University Edition and reopen JupyterLab.
