GET UID from firebase cloud functions

Question

Is there a way to get the uid when i trigger the storage events?

I want create a thumb when the image is uploaded in to firebase storage and then update the url of the user image profile in database...

exports.uploadphoto = functions.storage.object().onChange(event => {
  // ...
});

Two Options

You could store your image to a path that contains the uId then use event.data.name to get the file path

OR

Add it to the custom metadata when you upload, then access in cloud functions by:

const metadata = event.data.metadata
const uId = metadata.uId  

uId can be whatever you call it when you upload.
