Can you check that your version of npm is up to date? I think it would not be expected that this line is removed, and I think I've seen it only in older versions of npm.

[SammySteiner]

I was on npm v7.18.1, and node v16.4.2.
Should I update and publish again or do I need to delete the branch and start again?

[aduth]

No need to publish again. I think if you update npm, then run npm install on this branch, you should see a change that you just need to commit.

[aduth]

We also have a lint for this, which is currently failing.

Error: There are uncommitted changes after running 'npm install'
