Incorrect response.data/response.base64 for Android when using fetch

Hello @Traviskn @mheins57 After the latest 0.11.1 version release I have tried to add this new version to my project and fount possibly regression issue on Android:

When we are using

const response = await RNFetchBlob.fetch('GET', uri);
const imageData = response.data;
const imageBase64 = response.base64();

response.data looks broken, previuosly it was simple base64 string. response.base64() throws an error

Uncaught InvalidCharacterError {message: "The string to be encoded contains characters outside of the Latin1 range."}

In version 0.10.16 everything looks fine. On iOS both versions are working fine. I’m using react-native@0.61.1

As example i’m fetching this file: https://api-dev01.elateral-dev.io/file/dev01/S1GbfMFDN And get broken response.data instead of normal base64 string:

Could you please check this issue on Android please? Thank you

Hi @Traviskn @oleksandr-dziuban
I am trying with the lates version and the issue is still coming in android.

I am using `RNFetchBlob.fetch(‘POST’, REQUEST_URL, {

            'Accept': 'application/json',
            'Content-Type': 'multipart/form-data',
        },
        data
        )
        .then((response) => response.json())
        .then((responseData) => {
            console.log(responseData); })`

response data looks broken I’m using react-native@0.61.3

I am getting a broken response data instead of normal string. Example: Message: "تم التحميل بنجاح "

Ok, I’ll see about adding back the case for base 64 and opening a PR as soon as I can
