How to continue the iteration when solve routes fail?

Hi everyone,

I'm doing an iteration process to solve different shortest paths for different combinations of points. But the iteration stops when there is no solution for one combination. I think I may need if-else statement to check if solve fails, so I create a boolean variable "Terminate on solve error" to make it go through next step, but it still stuck at solve.

I'm new to python so don't know how to achieve this function. I attach the errors and part of the model in the screenshots. Does anyone have suggestions?
