I'm using this for uploading files to firebase my code looks like this:

 firestack.storage.uploadFile(userId+'/'+snap.key, path, {
 contentType: 'video/mp4',
 contentEncoding: 'base64',
 },

But in Firebase the folder has a trailing /, and i can't delete the files using firebase web sdk

my userid looks like this 1234567

but the folder is 1234567/
