[zulfi984]

I solved some unit tests Errors. But these things i cannot able to find out.

     Error: VM Exception while processing transaction: reverted with custom error 'InvalidConsumer()'

i found that some of my test got error due to this lines

 await raffle.performUpkeep([])

const tx = await raffle.performUpkeep("0x")

reverted with custom error 'InvalidConsumer()'
This error because of latest version and that I'm currently on @chainlink/[email protected]
downgrading to 0.4.1 using the following command eliminates this issue:
npm i @chainlink/[email protected]
