ERROR: Package Gurobi errored during testing

I am using Julia 1.6.1 and following are the packages installed:

BARON v0.6.5
CPLEX v0.7.7
Gurobi v0.9.12
Ipopt v0.6.5
JuMP v0.21.8

I am not able to understand the exact reason why these tests fail. Is it safe to ignore these tests or is there some package compatibility issue? Thank you.

[odow]

Previous versions of Gurobi (the solver) had a bug that caused incorrect solutions. I guess this means the fix was pushed through into the latest version. You can safely ignore these.

Got it. Thanks.
