#Hardhat errors

The most common source of errors is trying to import the Hardhat Runtime Environment from your config or a file imported from it. This is not possible, as Hardhat can't be initialized while its config is being defined.

You may also have accidentally imported hardhat instead of hardhat/config.

Please make sure your config file is correct.

#HH10: Attempted to modify the user's config

An attempt to modify the user's config was made.

This is probably a bug in one of your plugins.

Please report it to help us improve Hardhat.

#HH11: Invariant violation

An internal invariant was violated. This is probably caused by a programming error in hardhat or in one of the used plugins.

Please report it to help us improve Hardhat.

#HH12: Hardhat is not installed or installed globally

You tried to run Hardhat from a global installation or not installing it at all. This is not supported.

Please install Hardhat locally using npm or Yarn, and try again.

#HH13: ts-node not installed

You are running a Hardhat project that uses typescript, but you haven't installed ts-node.

Please run this and try again: npm install --save-dev ts-node

#HH14: typescript not installed

You are running a Hardhat project that uses typescript, but it's not installed.

Please run this and try again: npm install --save-dev typescript

#HH15: You are not inside a Hardhat project and Hardhat failed to initialize a new one

You are trying to run Hardhat outside of a Hardhat project, and we couldn't initialize one.

If you were trying to create a new project, please try again using Windows Subsystem for Linux (WSL) or PowerShell.

You can learn how to use Hardhat by reading the Getting Started guide.

#HH16: conflicting files during project creation

You are trying to create a new hardhat project, but there are existing files that would be overwritten by the creation process.

Either try using a new directory name, or remove the conflicting files.

#HH17: Invalid big number

Hardhat attempted to convert the input value to a BigInt, but no known conversion method was applicable to the given value.

#HH18: Corrupted lockfile

Some versions of NPM are affected by a bug that leads to corrupt lockfiles being generated.

This bug can only affect you if you, or someone at your team, installed the project without a lockfile, but with an existing node_modules.

To avoid it, please delete both your node_modules and package-lock.json, and reinstall your project.

Note that you don't need to do this every time you install a new dependency, but please make sure to delete your node_modules every time you delete your package-lock.json.

#HH19: Hardhat config with .js extension in an ESM project

Your project is an ESM project but your Hardhat config uses the .js extension. Hardhat config files cannot be an ES module. To fix this, rename your Hardhat config to use the .cjs extension.

#HH20: Initializing a TypeScript sample project in an ESM project

Your project is an ESM project (you have "type": "module" set in your package.json) and you are trying to initialize a TypeScript project. This is not supported yet.

#HH21: Uninitialized provider

You tried to access an uninitialized provider. This is most likely caused by using the internal wrapped provider directly before using it to send a request or initializing it. To initialize the provider, make sure you first call .init() or any method that hits a node like request, send or sendAsync.

#HH22: Invalid read: a directory cannot be read

An attempt was made to read a file, but a path to a directory was provided.

#HH100: Selected network doesn't exist

You are trying to run Hardhat with a nonexistent network.

Read the documentation to learn how to define custom networks.

#HH101: Connected to the wrong network

Your config specifies a chain id for the network you are trying to use, but Hardhat detected a different chain id.

Please make sure you are setting your config correctly.

Try using another mnemonic or deriving less keys.

#HH112: Invalid JSON-RPC value

One of your calls sent or received an invalid JSON-RPC DATA value.

Please double check your calls' parameters and keep your Ethereum node up to date.

#HH113: Invalid `data` param when calling eth_signTypedData_v4.

You called eth_signTypedData_v4 with incorrect parameters. Please check that you are sending a data parameter with a JSON string or object conforming to EIP712 TypedData schema.

#HH114: Incompatible fee price parameters

You are trying to send a transaction with a locally managed account, and its parameters are incompatible. You sent both gasPrice, and maxFeePerGas or maxPriorityFeePerGas.

Please double check your transactions' parameters.
