The sol contract and the deploy contract seems correct, I deleted artifact and cache several time and re-run it but always same issue. Am I missing some modules?

Here my repo:

make sure you have the contract "box.sol" (case sensitive) in the "contracts" folder.

[cryptocambi]

I did, is in capital B "Box" in the contracts folder and in the deploy file

[cryptocambi]

Found the mistake, made confusion with the folders.
I appreciate your help Omar

[omarhibshi]

No worries my friend, happy to hear this !

[alfaqi]

Try delete cache folders
cacheand artifact
Or run this command

yarn hardhat clean

[cryptocambi]

I did it, but always same error

[cryptocambi]

Alfaqi, thank for your help. Did find the mistake

Basically, made confusion with the folders.
