Are you using develop? Please make sure to use the tutorials/chain branch which trails develop because develop gets updated frequently. This is mentioned in the Build the Optimism Monorepo section of the tutorial but maybe needs to be made more obvious.

Yes, I made sure to checkout the correct branch, see below

Strange, will look into this...

I installed the latest (nightly) build of Foundry, is the missing file null.sol part of that package?

Can you try pnpm update:foundry? That will install the version of foundry used in that branch. Once you update, try pnpm clean then pnpm build again and rerun the deploy script.

Something's not right with the version in the repo 9e2830d7f0566e0d00b1104eeaedd5032a4e556e. Keeps erroring out with this when I try pnpm update:foundry or foundryup -C 9e2830d7f0566e0d00b1104eeaedd5032a4e556e

Doesn't happen with the nightly builds foundryup -v nightly-293fad73670b7b59ca901c7f2105bf7a29165a90

Can you try using version 84d9842? I just used that version on a clean install for the tutorial and it seemed to work.
