Unable to build with xcaddy when paired with caddy-maxmind-geolocation.

I seems to be unable to build caddy-tailscale with caddy-maxmind-geolocation.
Building them separately works fine but if I build them together the build fails with:

26.54 2024/09/06 11:55:23 [INFO] exec (timeout=0s): /usr/local/go/bin/go build -o /usr/bin/caddy -ldflags -w -s -trimpath -tags nobadger

------
failed to solve: process "/bin/sh -c xcaddy build     --with github.com/tailscale/caddy-tailscale     --with github.com/porech/caddy-maxmind-geolocation" did not complete successfully: exit code: 1

This is my Dockerfile:

FROM caddy:2.8.4-builder AS builder
RUN xcaddy build \
    --with github.com/tailscale/caddy-tailscale \
    --with github.com/porech/caddy-maxmind-geolocation
FROM caddy:2.8.4
COPY --from=builder /usr/bin/caddy /usr/bin/caddy

Maybe I'm doing something wrong here?

Start with the shown Dockerfile and reproduce the combined xcaddy build using caddy:2.8.4-builder. Read the reported failure in tailscale.com/net/tstun/wrap.go at line 965 and compare it with the separate builds. Done means the Docker build succeeds when caddy-tailscale and caddy-maxmind-geolocation are included together.
