The error is "Cannot perform the operation: {real affine} .* {convex}"

Hello all! Really need your help！
As shown in the following figure, the blue part is the two optimization variables in my code, but there is an error “Disciplined convex programming error: Cannot perform the operation: {real affine} .* {convex}” in T1(t,i) = d(t,i).*T(t,I) .
How can I solve it？

I don’t know whether your overall problem is convex because I don’t k now how T1 is used. Have you proven your optimization problem is convex?
