The problem goes away if direct_mode
isn't used. So far I tried to reproduce in a small problem and didn't happen.
are you sture this is SCIP-related? It seems like a JuMP error no?

We need a reproducible example, or the output of JuMP.solution_summary(model)
.
We only throw this error if the termination status is MOI.OPTIMIZE_NOT_CALLED
:
https://github.com/jump-dev/JuMP.jl/blob/509ab616192bc90891c329010e2205f414c8cf94/src/optimizer_interface.jl#L716-L719
SCIP maps SCIP_STATUS_UNKNOWN
to MOI.OPTIMIZE_NOT_CALLED
:
https://github.com/scipopt/SCIP.jl/blob/2d3897668d4f718f8a04e4a8d708ac938df48a93/src/MOI_wrapper/results.jl#L9
So perhaps the fix probably needs to happen in SCIP.jl. I don't know why the status would be unknown; it looks like the solver found a solution.
JuMP can't retrieve the result of a successful optimize! call giving the result below. It might be a case that the status is set incorrectly in the MOI wrapper.
