I'd need to see more of the definition of the function to find out what's
wrong, but clearly
{{-0.00004794 - 0.000020387I}}
is not a length 1 list of numbers, but a list of length 1 of lists of
length 1 (the double braces). For some reason, your function returns a
list of results. Use Flatten[] or First[] somewhere to get to {-0.00004794
- 0.000020387I}.
