Foundry Fundamentals Running Tests on Chain Forks

[EchoSpr]

When writing the test on the chain fork. I tried running this test.

 function testPriceFeedVersion() public {
        console.log(testFundMe.getVersion());
        uint256 version = testFundMe.getVersion();
        assertEq(version, 4);
    }

For some reason when I use console.log it is not printing out any information of the error. 
Here is the error that I am getting

  Ran 1 test for test/FundMeTest.t.sol:FundMeTest

Have you tried forge clean , deleting the cache folder, running foundryup, and then retrying the fork test?

What command do you run to run the test?

[EchoSpr]

forge test --mt  testPriceFeedVersion -vvvv  --fork-url $SEPOLIA_RPC_URL

After I continued with the lesson and did some refactoring the test ended up passing. I am not sure how that made it work, but thank you for your help!

Interesting, I am glad it is now working, at least.
