[SCIP] Error: constraint is not linear

[mahdi noorizadegan]

Hello,

I am implementing an IP using branch and price method.
When I want to get the dual value of constraints which are all linear, I
get the following error

[src/scip/cons_linear.c:17033] ERROR: constraint is not linear

What can be wrong?

Looking forward to hearing from you,
Regards,
Mahdi
