Lesson 9: imported VRF mock throwing warning and "from.toLowerCase is not a function" error

[Tosinkoa]

Here is the link to the repo: https://github.com/Tosinkoa/smart-contract-raffle

My contract was not deploying because I was getting this warning message from the VRF Mock I imported from chainlink, and also am getting an error that says from.toLowerCase is not a function.
The only place I used toLowerCase was in verify.js file.

The problem seems in your 00-deploy-mocks.js, check your code to see is it type correct

The problem was in my deploy file.
I did const deployer = await getNamedAccount() instead of doing const { deployer } = await getNamedAccount()
