CDF evaluated at random variable

Suppose that $Ysim F_Y$ is continuous. Then, we have: $P(Yleq y)=F_Y(y)$. We also have that $F_Y(Y)sim U_{[0,1]}$. But at the same time, $F_Y(Y)=P(Yleq Y)=1$.
So it seems to me that $F_Y(Y)=P(Yleq Y)neq F_Ycirc Ysim U_{[0,1]}$.
Is there a contradiction in my argument?
