react-native-fetch-blob for the application

Question

I do not know the reason. But the app stops. after finishing downloading the file. on android devices.

works fine until you finish the download

Does anyone have any suggestions?

export const downloadFile = (userUid, video, teacher) => {
  return (dispatch) => {



let download = '';
RNFetchBlob
.config({
  fileCache : true,
})
.fetch('GET', video.video, {
  Authorization : 'Bearer access-token...',
})
.progress((received, total) => {
    //alert('progress' + (received / total) )
  let progress = (received / total) *100
  dispatch({
    type:'progressDownload',
    payload:{
      key: video.key,
      progress: progress
    }
  });
})
// when response status code is 200
.then((res) => {
  //FIM DO CARREGAMENTO
 dispatch({
    type:'finishDownload',
    payload:{
      key: video.key,
      progress: 100,
      status: 'completed',
      locate: {
        path: res.path(),
      }
    }
  });
})
// Status code is not 200
.catch((errorMessage, statusCode) => {
  alert(errorMessage)
}) 

} }
