[Bug]: pouch models fail with voltage or power control

[rtimms]

PyBaMM Version

24.1

Python Version

3.11

Describe the bug

Pouch cell simulations with voltage or power control fail with the error

TypeError: Initial conditions cannot contain 'Variable' objects, but 'Variable(-0x4b072f39e284004e, Current variable [A], children=[], domains={})' found in initial conditions for 'Current collector current density [A.m-2]'

Steps to Reproduce

import pybamm

model = pybamm.lithium_ion.DFN(
    {
    "cell geometry": "pouch",
    "current collector": "potential pair",
    "dimensionality": 1,
    "thermal": "x-lumped"
    },
)


experiment = pybamm.Experiment(["Hold at 4.2 V until C/20 (5 seconds period)"])
sim = pybamm.Simulation(model, experiment = experiment)
sol = sim.solve()
