Why can't child component connect to redux?

Question

React

I have a component and if I call useSelector in it and display the store, then everything is fine, but for some reason such an error occurs in the child component, what is the reason for this?

I tried to wrap it in my provider separately, it doesn't help either

const PreviewCard = () => {
 //useSelector здесь работает
  return (
    <div>
      <PDFViewer style= {{width: '100%', height: '90vh'}}>
        <MyDoc /> //Внутри этого компонента уже нет
      </PDFViewer>
    </div>
  )
}

const MyDoc = () => {
  const formStore = useSelector(state => state.pdfFormReducer)// тут и происходит ошибка

  return (
    <Document>
      <Page size="A4" style={styles.page}>
        <View style={styles.sectionHeader} fixed>
            // тут просто формочки для pdf документа
        </View>
      </Page>
    </Document>
  )
  }
