Connection to Kubo via Unix domain socket fails with HTTP error

[ntninja]

Additional information:

• OS: NixOS 23.05
• IPFS Cluster version: 1.0.6
• Installation method: NixOS repo

Describe the bug:

When setting ipfs_connector.ipfshttp.node_multiaddr to the Multiaddr of the Unix domain socket exposed by Kubo Nix package by default ("/unix/run/ipfs.sock") IPFS Cluster Service appears to successfully connect to the socket but fails to make any HTTP requests instead printing the following error for each request:

error posting to IPFS:Post "http:///run/ipfs.sock/api/v0/id": http: no Host in request URL

This is probably an encoding issue when generating the URL before passing it to whatever HTTP library is used by ipfs-cluster-service, since the encoded “request URL” should read as “http://%2Frun%2Fipfs.sock/api/v0/id” according to that URL RFC and hence have a hostname (even if unusual) set.
