Android Download Manager - download happens succesfully but promise rejects

[Noitidart]

The download happens succesfully, even the notification is shown, using code:

        const res = await RNFetchBlob.config({
            addAndroidDownloads: {
                useDownloadManager: true,
                mime: mimeType,
                description: description || 'File from network',
                mediaScannable : true
            }
        }).fetch('GET', originalUrl, { 'Cookie':cookie });

However promise rejects for some file types (pdf) with: "Error: Download manager could not resolve downloaded file path."

Possible Unhandled Promise Rejection (id: 1):
Error: Download manager could not resolve downloaded file path.

I had the same issue. Add a path to the config.

    const res = await RNFetchBlob.config({
        addAndroidDownloads: {
            useDownloadManager: true,
            mime: mimeType,
            description: description || 'File from network',
            mediaScannable : true,
            path: RNFetchBlob.fs.dirs.DownloadDir + "/" + someFilename
        }
    }).fetch('GET', originalUrl, { 'Cookie':cookie });
