while following Hacking on Tangled
after nix run --impure .#vm and pushing to the dev knot.
loading the repo page fails with
ERRO appview/repo: ... calling knotmirror git.listBranches ...
https://mirror.tangled.network/... context canceled
appview/config/config.go:50 defaults TANGLED_KNOTMIRROR_URL to the public mirror nothing tells us to point it to the local knotmirrot on port 7007
i set export TANGLED_KNOTMIRROR_URL=http://localhost:7007 before running appview and it worked
