eslint error in React app persists after attempts to disable - reactjs

Question

I'm developing a Chrome extension using create-react-app. I've gotten my extension to load properly and communicate with the extension background. To get this working I had to flag the chrome global message for eslint.
// This works perfectly
/* global chrome */
let port = chrome.runtime.connect('extensionID',
{name: "bgconnect"})
// Background responses are handled here
port.onMessage.addListener(msg => {
console.log('Got message from background',msg)
if (msg.error) {
this.setState({error: msg.error})
}
})
When I try to add an additional chrome function using chrome.local.storage, however, I get
chrome.storage.local.get(['myKey'], result => {
if (result.myKey) {
this.setState({signedIn: true})
}
})
TypeError: Cannot read property 'local' of undefined
Here's what I've tried:
Verify manifest.js
...
"permissions": [
"<all_urls>",
"tabs",
"storage"
]
...
eslint 1
/* global chrome */
chrome.storage.local.get(['myKey'], result => {
if (result.myKey) {
this.setState({signedIn: true})
}
})
eslint 2
/* eslint-disable no-undef */
chrome.storage.local.get(['myKey'], result => {
if (result.myKey) {
this.setState({signedIn: true})
}
})
/* eslint-enable no-undef */
eslint 3
// eslint-disable-next-line
chrome.storage.local.get(['myKey'], result => {
if (result.myKey) {
this.setState({signedIn: true})
}
})
package.json
...
"eslintConfig": {
"extends": "react-app",
"globals": {
"chrome": true
}
},
...
I still get the same error despite making these changes.
One other weird thing is in console (Windows Powershell) it compiles, while normally when there is an error in the browser it's mirrored here. Instead the console output is:
Compiled successfully!
You can now view extension in the browser.
Local: http://localhost:3000/
On Your Network: http://10.0.0.110:3000/
Note that the development build is not optimized.
To create a production build, use npm run build.
Here's a screen shot of the error message. This happens in create-react-app when you run the app using npm start from the project folder.
