npx hardhat coverage --testfiles "test/gie-token-test.js" --network rinkeby

[Bhupesh-98]

I am trying to create coverage report of contracts I have created by running tests on rinkeby test network but facing problem stated below:

Command used -> npx hardhat coverage --testfiles "test/gie-token-test.js" --network rinkeby

The above command gives error : Error in plugin solidity-coverage: TypeError [ERR_INVALID_URL]: Invalid URL

same error here after upgrading from 0.8.2 -> 0.8.5, without a network specified (running on default hardhat

@clemsos Took a look at unlock and I see the error in your CI.

Would it be possible debug this by changing your coverage command in package.json to ?

hardhat coverage --network hardhat

This should coerce the task to use the built-in provider and help isolate the source of the problem (which might be in your network configuration logic).

hello @cgewecke, thank you very much for the answer. I just tried here unlock-protocol/unlock#12856 but no luck. I am still having thee same error

I'll double check my networks config

@clemsos Hmm, strange. Will take a closer look....

[cgewecke]

@clemsos Apologies, could you also bump hardhat up to the latest version? (I think you have it at 2.15.0).

There were changes at Hardhat and here to support an async provider creation pattern in #796 for 2.15.0 and maybe they had to patch something subsequently?

[clemsos]

Yes, this was a version issue with hardhat that has been fixed by upgrading it.. Thank you 🙏
