Error: Hardhat debugging not found

Troubleshooting Handbook for Hardhat Developers

Hardhat is a powerful development environment, but its error messages can be cryptic. Whether you're fighting stack-too-deep traces, nonce mismatches on forked mainnet, or ethers v6 type errors, this guide walks you through the root cause and the fix.

Common Errors & Fixes

1. HH1: Network doesn't exist Your hardhat.config.ts references a network not defined. Check networks in config and ensure the RPC URL is correct.
2. HH2: Cannot find module A plugin or dependency is missing. Run npm install and verify package.json includes all required Hardhat plugins.
3. HH8: HardhatTracer stack too deep Too many nested calls in a single transaction. Split your logic or increase the JS stack limit with --max-old-space-size.
4. RPC Error: insufficient funds The sender account doesn't have enough ETH for gas + value. Check account balance in hardhat node or fund the account.
5. ProviderError: execution reverted A require/assert failed or an out-of-gas occurred. Use console.log from Hardhat's built-in logger to trace where it reverts.
6. Nonce too high Transaction nonce doesn't match the expected on-chain nonce. Reset your wallet activity tab or clear nonce with hardhat reset.
7. Forking timeout The RPC endpoint for forking is slow or unreachable. Use a faster provider or increase blockGasLimit and timeouts in config.
8. TypeError with ethers v6 ethers v6 uses BigInt and named params instead of BigNumber. Replace .toString() with Number() or use formatEther.
