why i set a hard problem, it can be solved, while i set a very easy problem(0,0,0,0,0,.....), it cant be solved , and the estimate get larger and larger

status: primal infeasible
number of iterations: 975
run time: 4.70e-03s
optimal rho estimate: 4.29e+00

[OsqpEigen::Solver::solve] The solution is unfeasible.
