codegen: Error retrieving binary

[zramsay]

To reproduce:

• use bump solc version #421 to install codegen, then:

cd packages/codegen
git clone https://github.com/collectif-dao/liquid-staking.git

using this example.config.yaml:

contracts:
    # Contract name:
  - name: RewardCollector
    # Contract file path or an url:
    path: ./liquid-staking/contracts/RewardCollector.sol
    # Contract kind (should match name of dataSource in {subgraphPath}/subgraph.yaml if subgraphPath provided)
    #kind: Example1

# Output folder path (logs output using `stdout` if not provided).
outputFolder: ../coll/reward-collector

# Code generation mode [eth_call | storage | all | none] (default: none).
mode: none

# Kind of watcher [lazy | active] (default: active).
kind: lazy

# Watcher server port (default: 3008).
port: 3008

# Solc version to use (optional)
# If not defined, uses solc version listed in dependencies
solc: v0.8.21+commit.d9974be

# Flatten the input contract file(s) [true | false] (default: true).
flatten: true

# Path to the subgraph build (optional).
# Can set empty contracts array when using subgraphPath.
# subgraphPath: ../graph-node/test/subgraph/example1/build

# NOTE: When passed an *URL* as contract path, it is assumed that it points to an already flattened contract file.

The error:

# yarn codegen -c example.config.yaml 
yarn run v1.22.19
$ ts-node src/generate-code.ts -c example.config.yaml

same error for any contract

The solc version specified in example.config.yaml is incorrect.
It should be v0.8.21+commit.d9974bed
The list of solc versions is available in https://etherscan.io/solcversions

ah, trying now. My mistake was copying the GitHub short commit. If the pragma version is not correct, the error is different:

Error: ParserError: Source file requires different compiler version (current compiler is 0.8.13+commit.abaa5c0e.Emscripten.clang) - note that nightly builds are considered to be strictly less than the released version
