Optimisation of FourierCoefficients

I want to find the minimum of a Fourier-Coefficient as a function of the 
input values.

FindMinimum[Abs[Fourier[{ y, 1}][[1]]], {y, 2}]

The actual problem is a little more complicated, but even this simple 
statements gives the error messages I can't understand.

Fourier::fftl: Argument {y, 1} is not a non-empty list or rectangular array 
\
of numeric quantities.


Any suggestion ?

best regards

Edmund
