TypeError when trying to download file

[centotaure]

Hey everyone, I'm trying to get my app to download a file and open it with the default phone application, the simple fetch to get my file works however, as soon as i add this:

addAndroidDownloads : {
         useDownloadManager : true
 }

i get the following error : RNFetchBlob request error: TypeError: expected dynamic type 'string', but had type object'null

My code is below in case there's a mistake.
React Native version : 0.46.4
RN Fetch Blob version : 0.10.6

Snippet :

async _downloadFile () {
    await RNFetchBlob.fetch('GET', Global.baseUrl+'/'+this.file.webPath , {
        authorization : Global.appToken,
	addAndroidDownloads : {
            "useDownloadManager" : true
        }
    })
    .then(async(res) => {
        console.log('file downloaded');
    })
    .catch((err) => {
        console.log('error DLL : ', err.message);
    });
}

Thanks by advance, really nice library by the way it helped me a lot :)

For the record, that error message probably comes from this location, at least that's the only place I found :

https://github.com/wkh237/react-native-fetch-blob/blob/master/android/src/main/java/com/RNFetchBlob/RNFetchBlobReq.java#L431

You can find a lot of similar questions about the same kind of error if you google (link)

Apparently you have an object (null) where a string is expected. Yes, the question is where :-)

@centotaure Just an aside, there is no need to declare the first then() function as async - you don't use await, so it is useless.

Hi, did you find a solution ? I have the same problem :/
