Run npx hardhat compile to generate the typechain folder when using hardhat with solidity
As seen in the "Tasks" section of
I had a similar issue after deleting the the typechain folder
be sure to run the following command first:
npx hardhat clean or in my case yarn hardhat clean
from the documentation
Warning: before running it for the first time you need to do
hardhat clean, otherwise TypeChain will think that there is no need to generate any typings.
