no matching key/data pair found while running example full-contract-state

[NicolasWent]

Hello,

I am running the example: Full contract state

I am getting the following error:
RETH_DATADIR=/home/etharchive/eth/reth-datadir CONTRACT_ADDRESS=0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f cargo run --manifest-path examples/full-contract-state/Cargo.toml

Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.43s

Error: failed to open the database: no matching key/data pair found (-30798)

/rustc/ded5c06cf21d2b93bffd5d884aa6e96934ee4234/library/core/src/ops/function.rs:250:5

I am running my reth node like this: /home/etharchive/bin/reth node --full --datadir=/home/etharchive/eth/reth-datadir

My version of reth running the node was different from the repository version.

To solve

Step 1

Get the version the reth node is running, more specifically, the Commit SHA:

./reth --version
Reth Version: 1.9.2
Commit SHA: 74351d98e906b8af5f118694529fb2b71d316946
Build Timestamp: 2025-11-11T18:34:45.142585906Z
Build Features: asm_keccak,jemalloc,min_debug_logs,otlp
Build Profile: maxperf

Step 2

In the reth repository from which you want to run the example do:

git checkout 74351d9

(replace by your commit hash)

Step 3

Run the example again and it should work

RETH_DATADIR=/home/etharchive/eth/reth-datadir CONTRACT_ADDRESS=0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f cargo run --manifest-path examples/full-contract-state/Cargo.toml
