TypeError: Cannot read property 'getItem' of undefined

Description

I’m creating a new react-native project and when running it I’m getting the above error. The full error is:

TypeError: Cannot read property 'getItem' of undefined

This error is located at:
    in FlatList (at YellowBoxList.js:87)
    in RCTView (at YellowBoxList.js:79)
    in YellowBoxList (at YellowBoxContainer.js:36)
    in YellowBoxContainer (at YellowBox.js:147)
    in YellowBox (at AppContainer.js:104)
    in RCTView (at AppContainer.js:135)
    in AppContainer (at renderApplication.js:39)

Also, in my cmd I’m getting this error, related to the debugger:

I’m using windows 10. I understand that it might be related to my system because usually people init a new react-native app and it’s wokring. But I cannot figure out what’s the problem and why it responds like that. If you have a direction on what should I do I’d be glad to try anything, just a few days ago it worked fine and seems like it’s out of the blue.

Thanks a lot in advance

@kwoxer I actually need the @babel/plugin-proposal-class-properties as I’m using the @babel/plugin-proposal-decorators. Is there another solution to this issue?

[kwoxer]

Had the same issue.

Just remove:

     "@babel/plugin-proposal-class-properties": "^7.10.4",
     "@babel/plugin-transform-flow-strip-types": "^7.10.4",

from devDependencies

and

     plugins: [
       ["@babel/plugin-proposal-class-properties"],
       ["@babel/plugin-transform-flow-strip-types",
         {
           "loose": true
         }
       ],
     ],

from babel.config.js

Now build new.
