The goal of asymptotic safety is to find a well-behaved theory of quantum gravity via the existence of a non-Gaussian UV fixed point. The object favoured by the asymptotic safety community to investigate this is the effective average action. Upon finding an asymptotically safe theory using the effective average action, one would like to reconstruct a functional integral representation of the theory; this is known as the reconstruction problem. I will give a brief introduction to asymptotic safety, discuss the reconstruction problem and present a way to solve it.
