Originally created by @linuxkidd on GitHub (Oct 2, 2021).

Reproduction:

  1. Create two namespaces
  2. Add a host to each
  3. Share a host from one namespace to another
  4. Delete the shared host

Log output:

Oct 01 21:25:05 myhost headscale[2726810]: 2021-10-02T03:25:05Z ERR Cannot fetch peers error="invalid hex key (\"\"): length=0, want 32" func=getMapResponse
Oct 01 21:25:05 myhost headscale[2726810]: 2021-10-02T03:25:05Z ERR Failed to get Map response error="invalid hex key (\"\"): length=0, want 32" handler=PollNetMap id=XXXXXXXXXXXXXXXXXXXXX

Further, headscale -n NAMESPACE nodes list fails with:

2021/10/01 21:19:35 Error fetching shared machines: record not found

Only obvious way out was to wipe headscale db and start fresh, although I'm sure some sql queries could have cleared it. I'm just starting with headscale, so no reason to spend time salvaging the DB.

Ah good catch, @juanfont can you take a look at this?

We should probably also verify deleting nodes and shared nodes in the integration tests.
