Lesson 9

Unit test

While I'm testing entrance to the lottery during the lottery calculating state,
I'm getting back an error from VRFCoordinatorV2Mock

• 'InvalidConsumer()' custom error

$ npx hardhat test

snippet

seems it is triggerd with this line

await lottery.performUpkeep([])

Any pointers how can I fix this?
github-repo

Thanks for any idea

@martincapovcak Using Goerli should fix it, as Rinkeby has been facing issues lately.

@martincapovcak run npm i --save-dev @chainlink/contracts@0.4.1
