Dear JuMP community,
When I use Baron to solve a small-scale problem, I get an error of following form:
```julia

Does anyone know why I am getting this, by any chance? I checked the constraints, and the problem is feasible.
The command `optimize!(model)` works well, and I get this error when I check `termination_status(model)`.

I may be entirely wrong (and don’t have BARON to check) but it seems that there is `MOI.` missing from the code:
The yellow part should probably be `MOI.LOCALLY_SOLVED`. Open an issue with BARON.jl: [GitHub - jump-dev/BARON.jl: Julia wrapper for the BARON mixed-integer nonlinear programming solver](https://github.com/jump-dev/BARON.jl) ?

Wow! What a nice catch!! I don’t see this chunk of code in my local BARON.jl, though, any guess how I can find it?
Edit: found it: [BARON.jl/src/moi/results.jl at master · jump-dev/BARON.jl · GitHub](https://github.com/jump-dev/BARON.jl/blob/master/src/moi/results.jl)
