    Hi,

    I am running CPLEX 12.10 on Windows 11. I use the C# api to implement a cutting-plane algorithm, and the contextCallback to add some user cuts to the model. But it throws an exception: ILOG.CPLEX.CpxException: "CPLEX Error 1811: Attempt to invoke unsupported operation.. i have checked the user cut, the content is correct, nothing special.

    I wonder what's the problem that supposed to be.

    Sincerely, Jeff Yang
