Hardhat Ethers.getContract ("vrfCoordinatorv2mock") возвращает не определенные, даже если контракт составлен и развернут ⇐ Javascript

[Anonymous]

Я работаю над лотерейным проектом (лотереей) в сфере солидности с помощью Hardhat. На данный момент у него есть два контракта: < /p>

• raffle.sol
• vrfcoordinatorv2mock.sol
  Я создал скрипты развертывания как: < /li>
  />01-deploy-raffle.js
  Скрипт развертывания 01-deploy-raffle.js возвращает ошибку как:
  vrfcoordinatorv2mock объект undefined < /strong>, что означает ethers.getContract ("vrfcoordinatorv2mock") < /strong> natefined. Это более позднее приводит к неверной ошибке адреса.

Почему Ethers.getContract ("vrfCoordinatorv2mock") возвращается не определенным, даже если контракт развернут и составлен?>
