Question [Immersed Boundary Method] Error with turbulence model

Hello everyone, I am currently using the immersed boundary solver interIbFoam with Foam-extend 4.0 to solve a question with RANS turbulence model. I have made the case according to tutorials and started the simulation. Then it comes out an error with boundary conditions of turbulence coeffeciants. The error message is showing below.

    gradientInternalCoeffs cannot be called for a genericFvPatchField (actual type immersedBoundaryEpsilonWallFunction)
    on patch ibCylinder of field epsilon in file "/mnt/g/foam/thomaschi-4.0/run/cylBumpInterIbFoam/0/epsilon"
    You are probably trying to solve for a field with a generic boundary condition.

    From function genericFvPatchField<Type>::gradientInternalCoeffs() const
    in file fields/fvPatchFields/basic/generic/genericFvPatchField.C at line 832.

FOAM exiting

The problem relies on your boundary conditions. There is a boundary which is not consistent, so the simulation is under constrained.
