The problem is Pi is a symbol and RealDigits wants a number. Use
N to convert Pi to a number then use RealDigits. Also, the
fourth argument to RealDigits is expected to be an integer. So,
putting this together

In[3]:= RealDigits[N[\[Pi]], 10, 3, -9]

Out[3]= {{3,5,8},-8}

is the result I think you were looking for.
