error in tutorial 4

[YoungAgile]

https://docs.pybamm.org/en/latest/source/examples/notebooks/getting_started/tutorial-4-setting-parameter-values.html
In this tutorial, when i run those code, it return keyerror : 'Cannot update parameter 'Open-circuit voltage at 100% SOC [V]' as it does not have a default value. '

parameter_values["Current function [A]"] = 10
parameter_values["Open-circuit voltage at 100% SOC [V]"]=3.4
parameter_values["Open-circuit voltage at 0% SOC [V]"]=3.0

Should I use 'Upper voltage cut-off [V]'and 'Lower voltage cut-off [V]' to replace them?

Try doing

parameter_values.update(
    {
        "Open-circuit voltage at 100% SOC [V]": 3.4,
        "Open-circuit voltage at 0% SOC [V]": 3.0,
    },
    check_already_exists=False
)

Thank you! And should the code in the tutorial be updated

This should be automatically fixed in the new release
