I got a problem when i try to deploying a simple Solidity contract to zkSync Testnet using the zkSync Remix plugin

[seni7]

it shows
Expectation Failed
Solidity Verification Failed, logs can be read in the terminal log as a warning and
WARNING: You are currently using Node.js v22.11.0, which is not supported by Hardhat. This can lead to unexpected behavior. See https://hardhat.org/nodejs-versions

Hello @seni7, Did you put your file in the contracts folder, and are you working in the default-workspace of Remix? Also, clear your browser cache before retrying, as that always seems to help.

[KMean]

Hey @seni7 is it working without verifying it? try what @EngrPips said and if it doesnt work try to untick verify contract on remix before deploying it. You may want to verify it manually.

[fairuzStill-Learning]

in my case, i can do deploy the contract to zksync sepolia testnet and also interact with the contract but, i cant verifying the contract like @PatrickAlphaC do in the video or even manually, so i asked to cyfrin dc and they said isnt a big deal so i just move on learning but, still i wanna know why this happen.

[fairuzStill-Learning]

LOL i just fixed my problem
if ur contract folder name was contract change it into contracts and change solidity version to 0.8.24
and verify the contract directly in the remix like in the video.
idk why it worked, after 2 days concern bout this LOL

[fairuzStill-Learning]

now my contract verifyed

[ChiuMungZitAlexander]

Same here. But after I changed it to pragma solidity 0.8.24;, it worked.

[EngrPips]

Awesome! Thanks for the heads-up

Adding the file to the contracts folder and changing the Solidity version to 0.8.24 worked for me.

[EngrPips]

Awesome! Thanks for the heads-up

@EngrPips I have added the file to the contracts folder, cleared my cache, but it's only deploying and not veryfying, Please I'm stalked here, what can i do now?

[EngrPips]

Hello @H-code9, You can refresh your browser and retry, but if the issue persists, please continue with the course and don't bother with the verification.
