IPC transport - possible bug RelativeUrlWithoutBase

[mpazdzioch]

I think it may be a bug, at least I couldn't find a way to get graph-node working with IPC transport to geth node.

What is the current behavior?

To reproduce

cargo run -p graph-node --release -- \
  --postgres-url postgresql://postgres:password@postgres:5432/graph-node \
  --ethereum-ipc mainnet::ipc.socket \
  --ipfs ipfs:5001

ipc.socket is the unix socket file. It's a valid socket, confirmed using netcat I tried different path versions for ipc.socket, same dir as graph-node and other directories but it makes no difference. When I change --ethereum-ipc to --ethereum-rpc method using the same geth node (but http api) it works.

I confirm the same issue ethereum-ipc can't parse the filename ethereum-rpc works fine

I tried with file:///ethereum/geth.ipc and it says No such file or directory even though it exists and I can connect to it using socat.
