blocked_area,Why did it not take effect

I would like to ask why it did not take effect. I see that the planned route still passes through this blocked_area
Please help, thank you

It is obvious that my prohibited zone has not taken effect. Did I use the wrong method? I did write this according to the example, why is this? Please ask the Great God for help and guidance

A screenshot is not helpful for other people that might want to help. Please use simple text and put the whole code that you use into a code block (with ```).

I have the same problem, when the start and end points are very close, the avoidance zone will fail
