Perhaps you should consider posting the actual problem you wish to solve, or provide a different example, as the example you have posted has no solution. As I have indicated on your [previous post](https://fenicsproject.discourse.group/t/nodal-value-of-an-unknown-in-weak-formulation/6916/2), `term1` in this example is 0 by definition.

(The solution to ds/dx=0 is s(x)=s\_0, where s\_0 is a constant, which cannot satisfy the boundary conditions you have specified.)
