Someone else is trying to solve the same problem in FEniCSx so perhaps you can learn from them at [How to debug the PETSC ERROR?](https://fenicsproject.discourse.group/t/how-to-debug-the-petsc-error/13406). I **may** be solving coupled potential and concentration problem at the turn of the year. Good luck.
