Could you please leave a link to the Cyfrin Updraft Lesson (or YouTube video timestamp) where this error occurs? (You can right click a video and "copy video URL at current time")
I can't copy the video url timestamp but its from Episode 11 of Foundry FundMe: from 12:00 to 12:11, after we finished refactoring.
In episode 11 of Foundry FundMe, "Deploy a Mock PriceFeed" @ 12:11 , we run forge test --fork -url $MAINNET_RPC_URL and all the tests pass in the video but not for users following. This is outdated as this test function is asserting that the mainnet pricefeed version == 4. This is no longer correct. Chainlink updated the pricefeed verisons, so while the eth/usd sepolia pricefeed version is still 4, Chainlink's eth/usd mainnet priceFeed version is now 6. So the test testPriceFeedVersionIsAccurate should be changed to the following:
function testPriceFeedVersionIsAccurate() public {
if (block.chainid == 11155111) {
uint256 version = fundMe.getVersion();
assertEq(version, 4);
} else if (block.chainid == 1) {
uint256 version = fundMe.getVersion();
assertEq(version, 6);
}
}
This way if you run forge test --mt testPriceFeedVersionIsAccurate -vvvv --fork-url $SEPOLIA_RPC_URL or forge test --mt testPriceFeedVersionIsAccurate -vvvv --fork-url $MAINNET_RPC_URL the test will always pass.

Chainlink updated the pricefeed verisons, so while the eth/usd sepolia pricefeed version is still 4, Chainlink's eth/usd mainnet priceFeed version is now 6. So the testtestPriceFeedVersionIsAccurate
