Describe the bug

When running zkforge zkbuild --use 0.8.20 --use-zksolc v1.4.0 on a contract with a solidity syntax error the compiler crashes:

$ RUST_BACKTRACE=full zkforge zkbuild --use 0.8.20 --use-zksolc v1.4.0
The application panicked (crashed).
Message:  called `Result::unwrap()` on an `Err` value: Error("missing field `contracts`", line: 1, column: 316)
Location: crates/common/src/zk_compile.rs:1165

This is a bug. Consider reporting it at https://github.com/foundry-rs/foundry

Output of forge build on the same project for reference:

Was able to reproduce this with a few different types of solidity errors.

I have the same issue as you, too!! But it occurs when running the build command on any Solidity source, no matter if the code has correct syntax or no. I'm running Windows WSL, but @yohanelly95 is getting the same error on MacOS. (#285)

Hey folks 👋

We are in the process of releasing a new version of our Foundry implementation that will handle these situations much better. I apologize for the inconvenience currently being experienced, as this is an early alpha version we appreciate the reported issue. We are tracking to make a pre-release of the new version this week.
