The error message is quite explicit: downloadURL seems to be null. If you search for recent questions about this, you'll see that the download URL is now retrieved asynchronously by calling getDownloadURL().
So something like:
uploadTask.on('state_changed', function(snapshot){
// Observe state change events such as progress, pause, and resume
// See below for more detail
}, function(error) {
// Handle unsuccessful uploads
}, function() {
var postKey = firebase.database().ref('Posts').push().key;
var downloadURL = uploadTask.snapshot.downloadURL;
return storageRef.getDownloadURL().toPromise().then(downloadUrl => {
var postData = {
url: downloadUrl,
caption: $("#imageCaption").val()
};
var updatess = {};
updatess ['Posts' + postKey] = postData;
return firebase.database().ref().update(updatess);
});
});
Also see:
- the Firebase documentation sample on uploads
- the Firebase documentation on downloading files by URL
- How do i get download URL once upload is done on firebase storage
- Firebase get Download URL after successful image upload to firebase storage
- I can't get image downloadUrl from Firebase Storage (Angular/Ionic)
