@Cielo2021 A bunch of people ran into this problem (Me included).

No know solution was provided then but maybe by now it has been identified, I had to skip it and will circle back to it after the course is complete (Tag me if you find a solution please!)

[Cielo2021]

Will do @DorianDaSilva

Hello @Cielo2021

In my case there was problem with Chainlink Keeper setup as it has to be setup as custom one. you can also try to clone repository and try if it works once you update all details.

[Cielo2021]

Hey @Neftyr Thanks for your suggestions! I tried this but it didn't work.

[Nlferu]

Hi @Cielo2021

Hmm thats strange, do you see transactions on VRF as below:

And on Keepers (Automation) as below:

?

[Cielo2021]

Hey @neftyr I will give the VRF and Keepers another go and see what happens. Looking at your transaction I might of missed something. Thanks! I will let you know if I succeed. I might need to clone the repo and start from the beginning. Thanks a million!

Hello @Cielo2021. Here you can see the contract I deployed and in the Internal Txs tab you will see the invocations of performUpkeep and fulfillRandomWords.

Your code works fine, now there's something I don't understand, let me explain:

When I forked and cloned your repo I manually deleted the artifacts, cache, deployments, package-lock.json and node_modules folders. To have a clean slate. Then I ran yarn and installed the dependencies.

When I tried to compile with yarn hardhat compile I immediately got an error from hardhat telling me about a bunch of plugins that were missing, I checked the package.json file and indeed a lot of dependencies were missing more than half accordingly to hardhat.

The reason I'm saying all of this is: if all those dependencies were missing, I don't understand how managed to complete so much of the project without that error. Can you send a screenshot of your package.json?

[Cielo2021]

Thanks @pacelliv I will give this a try and let you know if it works.

[Cielo2021]

Hey @pacelliv - All your suggestions worked! I did have a few challenges.

For anyone reading this I had to add additional link tokens to VRF (10 Links) and Automation (18 Links).

I also changed the time to
mocha: { timeout: 100000000, },
It seems that the networks might been down, cause I am currently stuck on a message that says pending/waiting!

[pacelliv]

Hello @Cielo2021, I'm happy to see we managed to make the code work. I'm sure increasing the timeout made a big difference.

for any1 who is finding hard to solve, follow these steps:
Manually delete the: artifacts, cache, deployments, node_modules folders and the package-lock.json file.
Replace your current package.json file as given above
