Cast storage not working as expected: Getting different output(null) while expecting the bytes output of myPassword

[skpkss]

Video lesson: https://updraft.cyfrin.io/courses/security/first-audit/proof-of-code?lesson_format=video
I am doing the password store audit. Currently, i am building on proof of code to show that private variable are not actually private. but when i am running the cast storage command it is displaying me the bytes of null instead of 'myPassword'

Hello @skpkss, I am convinced this is more a Foundry issue than the course issue. Please check the official Foundry GitHub to see if any similar issue has been reported recently.

[EngrPips]

You can also try running foundryup and then retry. Maybe that will help.

[skpkss]

I have already tried it.It's not helping.

[EngrPips]

I see. Did you find a recent report of a similar issue on the official GitHub page of Foundry?

[skpkss]

no. is this has to do something with the version of make? i am using 0.8.1

[EngrPips]

I think at a point in the past, this was an issue with Foundry. Around May Foundry update or so I think, but I haven't seen anyone run into this issue of recently.

Can you run this at your end? My forge version is forge 0.2.0 (a0a0020 2024-08-12T00:25:05.209264900Z)

[EngrPips]

I have this

forge --version
forge 0.0.2 (1cf88dc 2024-08-21T00:21:46.971220000Z)

[EngrPips]

I ran foundryup, and now my versions are below.

[skpkss]

i have the same foundry version. Can you run the cast commands in this lesson: https://updraft.cyfrin.io/courses/security/first-audit/proof-of-code?lesson_format=transcript and please share the output?

[EngrPips]

So I did as you instructed here is my output

It seems to work properly for me.

[EngrPips]

Alright, Please read this Ethereum stack exchange post https://stackoverflow.com/questions/32127524/how-to-install-and-use-make-in-windows on how to install make for Windows.

[skpkss]

this is the make deploy command:

deploy:
	@forge script script/DeployPasswordStore.s.sol:DeployPasswordStore $(NETWORK_ARGS)

[EngrPips]

I will search for a proper guide on how to install make for Windows and get back to you with whatever I find.

[skpkss]

Hey @EngrPips the issue was resolved.First of all, i installed scoop from https://scoop.sh/ by running commands on powershell. And after that searched for make and ran the make installation commands on cmd.

[EngrPips]

Interesting, Most of the time, our solution is not far-fetched, only if we can put in a little more effort! Keep crushing buddy
