Failed prop type. Required prop types are undefined in my redux store


Failed prop type. Required prop types are undefined in my redux store

around this issue So I'm learning react and redux and I get this error in the console whenever I load my page. I'm not sure what it means since my store should be connected properly (as far as I know, but obviously it's not).
code :
const mapStateToProps = (state: any) => ({
    open: state.open,
})
{
  content: {
    open: // some boolean
  }
}
const mapStateToProps = (state: any) => ({
    open: state.content.open,
})
// in the file with the root reducer:
const rootReducer = combineReducers({
    content: ContentReducer
});
export type RootState = ReturnType<typeof rootReducer>;

// And then use it elsewhere like:
const mapStateToProps = (state: RootState) => ({
    open: state.content.open,
})

To fix this issue Check what’s in state.notes. You could log it or set a breakpoint somewhere and use your browser’s debugger.
It seems the objects in that array don’t have a text property or it’s set to undefined or null. You might have a typo where that value should be set.

hope this fix your issue I briefly looked over your code, and I believe you're not getting that id because you're not importing the action creator function you think you are.
in containers/AddTodo.js:
code :
import { addTodo } from '../actions'
./src/actions.js
./src/actions/index.js

it helps some times You export store as default: export default store;
You need to import it this way: import store from './Store/Store'
code :
// file.js
export a;
export b;
export default c;

//otherfile.js
import c, { a , b} from './file';

I wish did fix the issue. First option is that you can set this.descriptionText to a default value like an empty string or something on constructor
code :
constructor(props) {
  super(props);
  this.descriptionText = 'some default value or empty string';
}
message={this.descriptionText || 'some default value or empty string'}

it helps some times It seems that you are doing even if options is undefined. This basically translates to initialising that component (but not calling the render function). During initialisation, react will check that all required props are available which is then throwing an error.
To fix it, I would do the following:
code :
const mapSignUpComponents = {
            text: (
                <TextInput  
                  placeholder={placeHolder}
                  number={number}
                  style={[{color: defaultColor, borderColor: defaultColor}, styles.defaultTextInputStyle, templateStyle]}
                  onChangeText={text => onChangeHandler(text)}
                  value={payload[key] ? `${payload[key]}` : ''} // Doesn't seem right but otherwise the value of the text input also get mutate with other values
                />),
            dateTyper: (
              <DateTyper
              textInputStyle={[{color: defaultColor, width: (Dimensions.get('window').width * 0.6)/8 }, styles.nextInputStyle, templateStyle]} 
              upsideEmit={onChangeHandler}/>
            ),
            checkboxes: options === undefined ? undefined : (
              <CheckBoxes 
              options={options}
              />
            )
          }
