Error Simulink Coder "cannot be defined to be a periodic function-call block because it has an asynchronous rate."

I need to build a model thanks to simulink, but the problem is when I do it, I have this error: "cannot be defined to be a periodic function-call block because it has an asynchronous rate."

I found where it came from, this is due to 2 delay time (one Variable Time Delay Block and one Transport Delay), I tried to build the model without those blocks and Simulink compiles. But I have to put those Delay Time in my model otherwise this is false.

Do you know what can I do ?

Thank you in advance.
