Hello @Aishwaria8786, only with the error message is going to be difficult to help you, can you format your question according to these recommendations?

I am in lesson 9.I run forge test and all test passed. But when I am running forge test --fork-url $SEPOLIA_RPC_URL ,it is showing this particular problem.

Verify if the variables that you're using are avaliable on the testnet. Also verify If you're doing a call to fulfillRandomWords or something similar that you're not allowed to do on a testnet.

Without seeing any code, code this also be a set up issue with Chainlink or the private key?

I personally had this same error, but I was only getting it while testing locally (forked was fine). I missed adding deployerKey to the createSubscription functions.

[Aishwaria8786]

I surprisingly solved the issue by by changing the subscriptionid to 0 in helperConfig.s.sol file . I would like to advise all to watch Patrick sir's video slowly.

Don't forget to mark this answer as the solution,

I found the actual solution which is I create subscription on chainlink from one account but in env file I put private key of another account.I corrected it now it works fine with subscriptionid .
