I've started working with firebase storage and firebase functions recently. Right now I've been developing file upload from functions to storage .
I've got it working (upload is done and file appears on the storage section), yet, the image, stays like this forever (loading forever on the right side):
I though that it was an error from my code. Yet, if I open Google Cloud Platform - Storage, the image appears and I can open it and preview it.
In firebase storage, if I open the image (select on it and click open), it returns the following url: https://console.firebase.google.com/u/0/undefined
What may I been doing wrong? Here's the code I'm using:
function uploadImage() {
const newImageData = "data:image/png;base64,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"

Thanks for the help
Haven't been able to test the solution given by Firebase, but here's the transcript of the response:
The problem that you are facing could be because of two reasons. The first one is how you are uploading the files, via the Firebase Console, using any Admin SDK, or via the gsutil command. If using the Admin SDK option, the problem is a known issue where the required metadata doesn’t exist, fortunately there is a workaround, you can try this script to solve this issue.
Now, the second one is related to the network if you are using comcast, please, try on a different network to see if this issue is related to that.
When you save an image to firebase, you need to provide an access token in metadata : firebaseStorageDownloadTokens
. It has to be an uuid
.
More info can be found here : https://www.sentinelstand.com/article/guide-to-firebase-storage-download-urls-tokens
const { v4: uuid } = require("uuid")

After that you'll need to click on "Create access token"
@jean-smaug answer is almost complete. Based on the page he linked (https://www.sentinelstand.com/article/guide-to-firebase-storage-download-urls-tokens), the only missing thing is to wrap the firebaseStorageDownloadTokens
property inside a metadata
object. I've just tested it and it's working fine 👌 No need to create access token afterwards.
