Verifying Contract deployed through script

[IbrahimSam96]

I'm running a simple script to deploy my contract.

forge script script/Deploy.s.sol  --broadcast --rpc-url $AVALANCHE_DEVNET_CONNECTION --private-key $DEPLOYER --etherscan-api-key $SNOWTRACE_API_KEY --verify 

The contract gets deployed successfully. However, I get this error back!

We haven't found any matching bytecode for the following contracts: [0x....].

This may occur when resuming a verification, but the underlying source code or compiler version has changed.

One of my libraries imported another library using a relative import (e.g. @openzeppelin-contracts). Because of some versioning issues (where I needed to install openzeppelin-contracts at a specific version in my repository's gitsubmodules), I decided to set the relative import path in my remappings.txt as follows, which caused issues when attempting to verify a proxy contract imported from openzeppelin.

@sp1-contracts/=lib/sp1-contracts/contracts/src/
@succinctx/=lib/succinctx/contracts/src
@openzeppelin/=lib/succinctx/contracts/lib/openzeppelin-contracts/
@openzeppelin-upgradeable/=lib/succinctx/contracts/lib/openzeppelin-contracts-upgradeable/

After trying a bunch of different things recommended by #5170, #4865, I decided to install the dependencies that I needed directly. I retrieved the version required by my succinctx dependency for the openzeppelin contracts and installed it in my Foundry project, rather than using remappings.txt to access a nested submodule.

After changing it to this, my Proxy contract from openzeppelin verified:

@sp1-contracts/=lib/sp1-contracts/contracts/src/
@succinctx/=lib/succinctx/contracts/src
@openzeppelin/=lib/openzeppelin-contracts/
@openzeppelin-upgradeable/=lib/openzeppelin-contracts-upgradeable/

Banger. Yeah I remember still getting a tough time verifying contracts while deploying, will try this out and let you know!

Also curious to know. Are you still hiring for the Frontend Developer role ? I'm really passionate about crypto and I'm very good with working across the full stack. (Frontend ----> Bakcend ----> Contract).
