The final g is all 0

[yueshinian]

Hello, I want to know which constraint was violated when the solution failed. So I obtained g from the interface finalize_solution(). But I found that the values of g are all 0. May I ask why this is happening, and is there any way to avoid this situation?
Any help would be greatly appreciated.

Doesn't happen for me.

What does "solution failed" mean? How did it fail, which status code, etc? Is the final solution indeed not feasible? Do the constraints in the final iterate, if any, have values different from zero? ....
