Unable to use explicitPorositySource with fvOptions in driftFluxFoam
 

I'm running a simulation using driftFluxFoam and it runs okay without fvOptions active. However, when explicitPorositySource is activated, the simulation crashes with the following error:

request for volScalarField nu from objectRegistry region0 failed
available objects of type volScalarField are
