Blueprint Interface sharing variable isn't work on server side

I use blueprint interface to send message , from Controller to animationBP
for example , Controller have event that detect the fire button is pressed , and by using blueprint Interface
I sent the bool to animationBP , and trigger the state .
however it won’t work on server side , only local effect .
I know it’s the “sending Variable by Blueprint interface” goes wrong , because other animation without it , work fine .

This is Mycharacter , I set those variable to be sending .

And this is my AnimationBP event graph , I simply exec the bpi funcion to get those variable update .

Is there any way to fix it ? or simply I shouldn’t send variable by BPinterface ?
