I am currently unable to compile the Solidity contracts or unit tests, primarily due to usage of
Arrays.sort()
, which isn't present in version 5.0.1 of the OpenZeppelin contracts. I think this is due to the missingpackage-lock.json
file, which means the npm install is unpredictable.This updates the version of the OpenZeppelin dependency to 5.1.0 and adds back the
package-lock.json
file, so thatArrays.sort()
is available. It also aligns the Solidity version pragma with the current version in the Hardhat config.
