Lesson 7: VRFConsumerBase & VRFConsumerBaseV2 & REMIX - out of gas exception

[rkovrigin]

Guys, I have some GoerliETH on my account - 1.2338
I was able to deploy the contracts - VRFv2Consumer and RandomNumberConsumer via REMIX
But when I try to send some ETH to the contracts addresses I got - "Warning! Error encountered during contract execution [out of gas] ".
I checked I send less than I have on my account.
The transaction - https://goerli.etherscan.io/tx/0xd0505fe178861dc67e6b16cd0db5399a01405fdc0010a19f47153d8aa413c8b8
You can check that the address I send the ETH from has some gas

Hello @rkovrigin
As I remember you have to first perform subscription (basically add your account to chainlink) then you have to fund it with some LINK instead of ETH and at last, you have to add deployed contract address to that subscription account you have added in first step, so this deployed contract can use LINK you funded to subscription account. Then it will be able to generate random number for you.

Also remember to pass correct ID from subscription, you can read it as showed below:

You can also follow below video as it shows above steps in details:

This is the correct answer, does this make sense for you @rkovrigin?

Hello @Neftyr & @cromewar
@Neftyr , I did what you have mentioned, indeed I didn't connect my Metamask with ChainLink, so I can see I have some balance.

But still have the same Error.

Do I have to do anything on a Metamask side, connect ChainLink account, or smth like that?

[rkovrigin]

Ooops, sorry.
So, I tried to fund my contract with GoerliETH, but it is incorrect.
I had to fund it with LINK, as @Neftyr mentioned. I just could not figure how to do so via MetaMask browser extension UI.
Apparently, first I had added the ChainLink tokens via Assets->Import Tokens, after that MetaMask UI let me do that.
Thanks @Neftyr !
