Extended eslint configuration is not behaving as expected

[Ethan-Arrowood]

In my CRA (react-scripts v3.4.1) I have extended eslint in my package.json with:

{
  "eslintConfig": {
    "extends": "react-app",
    "rules": {
      "semi": ["error", "never"],
      "indent": ["error", "tab", { "SwitchCase": 1 }],
      "quotes": ["error", "single"]
    }
  },
}

The property in question is "indent" which is configured for use with tabs and 1 tab indent for case blocks in switch statements.

My .env file also contains: EXTEND_ESLINT=true

Now my editor (VSCode) doesn't complain, but when I run npm run start I get an eslint error related to the switch case indentation:

Failed to compile.

./src/App.tsx
  Line 29:1:  Expected indentation of 4 tabs but found 5  indent
  Line 30:1:  Expected indentation of 5 tabs but found 6  indent
  Line 31:1:  Expected indentation of 5 tabs but found 6  indent
  Line 32:1:  Expected indentation of 4 tabs but found 5  indent
  Line 33:1:  Expected indentation of 5 tabs but found 6  indent

For reference here is the component containing the block its referencing:

const Main = () => {
	const [ profile, setProfile ] = React.useState<any>()
	const [ error, setError ] = React.useState<any>()

	React.useEffect(() => {
		fetch(`/api/profile/${crypto.randomBytes(16).toString('hex')}`)
			.then(res => {
				if (!res.ok) {
					throw Error(res.statusText)
				}
				res.json()
			})
			.then(res => {
				setProfile(res)
			})
			.catch(err => {
				switch (err.message) { // line 29
					case 'Not Found':
						setError('User Not Found')
						break
					default:
						setError(err.message)
				}
			})
	}, [])

	return (
		<main>
			<h2>Profile</h2>
			<pre><code>{JSON.stringify(error || profile, undefined, 2)}</code></pre>
		</main>
	)
}

Any ideas what I'm doing wrong?

Of course after I post I manage to fix it... all I did was SHIFT+TAB and then TAB over the inner part of the switch statement and it fixed itself. Very strange behavior... maybe caching or something up with TS? I'll leave this open so someone else can comment if they have further ideas or whatever.
