[op-node] l1.rpckind=reth_db fails even when compiled with rethdb tag

[olivain]

Hi there,

On my debian, I followed the instructions of this page:
https://paradigmxyz.github.io/reth/run/optimism.html
in order to compile op-node locally with the rethdb-reader dylib:

git clone git@github.com:ethereum-optimism/optimism.git
cd optimism/op-service/rethdb-reader && cargo build --release
cd ../op-node
go build -v -tags rethdb -o ./bin/op-node ./cmd/main.go
mv bin/op-node /usr/bin/op-node

Compilation went well with no issues. But when i try to run op-node with the following flags:

--l1.rpckind=reth_db --l1.rethdb=/root/.local/share/reth_data/db

op-node fails with the following error :

msg="Application failed" message="invalid value "reth_db" for flag -l1.rpckind: unknown rpc kind: "reth_db""

Is the rethdb-reader still a thing ? is the tutorial i followed outdated ? Is there any way to precise to op-node that the l1 rpc runnng locally is reth ? What am i missing here ?

--l1.rethdb has to be set to a non-empty value, and the build flag should be used, for the reth DB to be used. There's no such thing as a reth_db RPC Kind as far as I am aware, but this may have been simplified as part of prior reth-db related changes.
