I am using react-native-blob-util because rn-fetch-blob has not been updated since 5 years ago and I have this error which happens with rn-fetch-blob too:
TypeError: null is not an object (evaluating 'ReactNativeBlobUtil.DocumentDir')
I am using react-native 0.68.1 and this only happened on android and not iOS.
If someone has already faced the issue.
"react-native": "0.68.1",
"react-native-blob-util": "^0.16.0",
