  let options = {
            fileCache: true,
            appendExt : ext,
            IOSBackgroundTask: true,
            trusty : true,
            addAndroidDownloads : {
                useDownloadManager : true,
                notification : true,
                path:  fs.dirs[path] +"/"+row.fileName.slice(0, row.fileName.length -5)+'_'+Math.floor(date.getTime() + date.getSeconds() / 2)+'.'+ext,
                description : row.fileType.slice(0, 5),
                mime: row.fileType,
            }
        };

        config(options).fetch('GET', linkDownload ).then((res) => {
            console.log(res)
        }).catch((e) => {
            console.log(e)
        });

I'm getting this error

value for title cannot be cast from readablenativemap to string

if I change fetch to this 

fetch(linkDownload, {
    method: 'GET',
  })

I will get different error this

com.facebook.react.bridge.ReadableNativeMap cannot be cast to java.lang.String

Can anybody help me with this? thank you for your time.
