File-based uploads in .netlify/blobs/deploy do not work

Support
1

My site name is https://master--catchthemoment.netlify.app/

I put some blob files and metadata on .netlify/blobs/deploy. I can see those files in GitHub. I think the path is correct. Deploy is successful without any errors. But I cannot see those files in blobs.

I also try to “ls .netlify/blobs” in the build command, but this folder is empty.

This is my netlify.toml

# Base build settings that apply to all environments
[build]
  publish = "catchthemoment-app"
  functions = "catchthemoment-app-functions"

# Settings for the PRODUCTION environment
# This applies when you deploy to your main site URL
[context.production.functions."*"]
  netlify_blobs = ["audio-uploads"]

# Settings for DEPLOY PREVIEWS (your UAT environment)
# This applies to all pull/merge request previews
[context.deploy-preview.functions."*"]
  netlify_blobs = ["audio-uploads-uat"]

Do not know why it is not uploaded. I think Netlify does not even try to download it from GitHub.

This is invalid config. However, I could reproduce the issue, and I’ve filed it for the devs.

Thanks for your reply.

Could you please let me know what the problem is with my config? How can I fix it?

5

There’s no solution at the moment. Like I mentioned, I’ve filed it for the devs. Will let you know once they respond.

6

Have you tried using the Frameworks API for this: Frameworks API | Netlify Docs?

7

I know the API work. But I want to use File upload to restore the backup. I may have more than 10k files need to restore. I think file upload is easier and faster.

Does it has a way to backup and restore blobs file with metadata?

8

@hrishikesh Any update on this?

9

None yet, and given the schedules of the devs, I don’t anticipate any movement on this for the time being. This is a low-priority issue right now.
