Question: ode system is singular at the initial point

Could you help me how to deal with this problem?

restart;

with(plots):with(plottools):with(DETools):

 

Sys:=diff(T(R),R)=((1-1/R)*(sqrt(1-(alpha/R)^2*(1-1/R))))^(-1),diff(Phi(R),R)=(alpha/R)^2*(sqrt(1-(alpha/R)^2*(1-1/R)))^(-1);

diff(T(R), R) = 1/((1-1/R)*(1-alpha^2*(1-1/R)/R^2)^(1/2)), diff(Phi(R), R) = alpha^2/(R^2*(1-alpha^2*(1-1/R)/R^2)^(1/2))

(1)

 

inits:=[[T(0)=0.5,Phi(0)=0],[T(0)=0.5,Phi(0)=Pi/4]];

[[T(0) = .5, Phi(0) = 0], [T(0) = .5, Phi(0) = (1/4)*Pi]]

(2)

K:=dsolve([Sys,op(op(1,inits))],[Phi(R),T(R)],numeric,parameters=[alpha],output=listprocedure);

Error, (in dsolve/numeric/make_proc) ode system is singular at the initial point
