hop of those help? So it looks like the module isn't importing. Obvious I know, I can only think of a few things to help seeing as that project looks fairly popular and stable.
I noticed that you're requiring 'react-native-file-uploader' but using 'react-native-fetch-blob'. I'm assuming this is a mistake. You could also try, if you haven't:
React Native [Android] URI from Google Drive w/ 'React-Native-Document-Picker' & 'react-native-get-real-path'

React Native [Android] URI from Google Drive w/ 'React-Native-Document-Picker' & 'react-native-get-real-path'

like below fixes the issue Fixed bug to get absolute path of Google Drive File.
So it turns out that we cannot directly get the absolute path from the URI that has been returned by selecting Google Drive File. Hence we need to apply some sort of hack to solve the problem.
code :
input = context.getContentResolver().openInputStream(uri);
/* save stream to temp file */
/* displayName is obtained from the URI */
File file = new File(context.getCacheDir(), displayName);
OutputStream output = new FileOutputStream(file);
byte[] buffer = new byte[4 * 1024]; // or other buffer size
int read;

while ((read = input.read(buffer)) != -1) {
  output.write(buffer, 0, read);

final String outputPath = file.getAbsolutePath();
return outputPath;

I think the issue was by ths following , In new version of react-native-document-picker@3.2.4. They changed method names earlier versions of document picker we import DocumentPicker and DocumentPickerUtil both methods, but in new version of this npm we will import only one method DocumentPicker.
Replace this
