[mohammdwaqas]

i am getting above error while trying this code to upload image to firebase

`function uploadImage() {

        return new Promise((resolve, reject) => {
            let imgUri = 'content://com.google.android.apps.photos.contentprovider/-1/1/content%3A%2F%2Fmedia%2Fexternal%2Fimages%2Fmedia%2F80/ORIGINAL/NONE/1685675380'; let uploadBlob = null;
            const uploadUri = Platform.OS === 'ios' ? imgUri.replace('file://', '') : imgUri;

            const imageRef = firebase.storage().ref();
            const name = 'myimg';
            mime = 'image/jpeg';
            fs.readFile(uploadUri, 'base64')
                .then(data => {
                    return Blob.build(data, { type: `${mime};BASE64` });
                })
                .then(blob => {
                    uploadBlob = blob;
                    return imageRef.put(blob, { contentType: mime, name: name });
                })
                .then(() => {
                    uploadBlob.close()
                    return imageRef.getDownloadURL();
                })
                .then(url => {
                    resolve(url);
                })
                .catch(error => {
                    reject(error)
                })
        })
    }`

I found one place (addCompleteDownload) where getString was called on a ReadableMap without a check if the path key exists. I will submit a pull request.

I am getting same issue when i add below code snippet .
//
window.Blob = Blob;

I just solved it following rainbarrel's solution at wkh237#634, doing the same for window.Blob, because I got the "unsupported bodyinit type" error right after the mentioned solution.

You can try this:
replace:
const uploadUri = Platform.OS === 'ios' ? imgUri.replace('file://', '') : imgUri;
To:
const uploadUri = imgUri;
This work for me (on android).
