Lesson 15:Error HH8: There's one or more errors in your config file

[BrysonHall]

When I`m trying to compile my files I get this error :

Error HH8: There's one or more errors in your config file:

  * Invalid value undefined for HardhatConfig.networks.etherscan.url - Expected a value of type string.
  * Invalid value undefined for HardhatConfig.networks.gasReporter.url - Expected a value of type string.
  * Invalid value undefined for HardhatConfig.networks.contractSizer.url - Expected a value of type string.
  * Invalid value undefined for HardhatConfig.networks.namedAccounts.url - Expected a value of type string.
  * Invalid value undefined for HardhatConfig.networks.solidity.url - Expected a value of type string.
  * Invalid value undefined for HardhatConfig.networks.mocha.url - Expected a value of type string.

I have my .env in the right place.

Make sure that your .env matches the hardhat.config,js. I recommend copying the hardhat. config from the repo from lesson 15 and make sure it matches the .env.

[BrysonHall]

Copying the hardhat. config from the repo and ensuring it matched the .env fixed the problem. Tnx.

Make sure in your .env the format is Object ie: RINKEBY_RPC_URL=https://eth-rinkeby.alchemyapi.io/v2/
PRIVATE_KEY=
i had colons between instead of = wasnt working gave me HH8 error
