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.
![the content of the user cut](https://higherlogicdownload.s3.amazonaws.com/IMWUC/UploadedImages/tlA5ZEyzSoGGigZr9S1Y_屏幕截图 2023-01-11 030343-L.png)
I wonder what's the problem that supposed to be.
Sincerely, Jeff Yang
