Lesson 9 : Problem while deploying mock ERROR : const { deployer } = await getNamedAccounts() ^^^^^^^^ SyntaxError: Identifier 'deployer' has already been declared

[GitAniket98]

Getting this error in 00-deloy-mocks.js :
Error: ERROR processing skip func of /home/aniketchow/hardhat-smart-contract-lottery/deploy/00-deploy-mocks.js: /home/aniketchow/hardhat-smart-contract-lottery/deploy/00-deploy-mocks.js:9 const { deployer } = await getNamedAccounts() ^^^^^^^^
Here is my 00-deploy-mocks.js :
