There is this general result that for any metric $ds^2$ that is asymptotically $AdS_{d+1}$, then there is a coordinate system in which
$$
ds^2 = \frac{1}{r^2}(dr^2 + g_{ij}(r,x^k)dx^i dx^j)
$$
where $g_{ij}(r,x^k)$ admit the following expansion close to the (conformal) boundary of $AdS_{d+1}$:
$$
g_{ij}(r,x^k) = g^{(0)}_{ij}(x^k) + \frac{1}{r} g^{(1)}_{ij}(x^k) + O(r^{-2})\, ,
$$
the boundary being at $r\to\infty$ and $1\leq i,j,k \leq d$.

[The above expansion can also contain some $r^dlog(r)$ when $d$ is even.]

I now assume that the metric satisfies Einstein's equations with some non-trivial stress-energy tensor.

I guess the radius of convergence of the above series depends on the stress-energy tensor.

My question is: how does the convergence radius depend on the stress-energy tensor?
