"An Error Occurred, undefined is not an object..."

[dowidubai2-9714 (dowi)]

I team,

When I try to share a project in v0, I get the following error and the share link doesn’t work:

An Error Occurred, undefined is not an object (evaluating ‘a.project.id’)

What I was doing

• Opened my project in v0
• Clicked Share to generate a public link
• Copied the link and tried to open it (or send it to someone)

What I expected
The shared link should open the project preview for anyone with the link.

What actually happens

• I see the error above in the UI
• The generated link sometimes points to an invalid resource and fails to load

Environment

• Browser: Chrome (latest stable) on macOS
• Region/Time: UAE (GMT+4)
• Logged in to Vercel with a single account

Thank you for your help.

Our docs are a great place to start.

Getting Started Using v0 is like chatting with a frontend engineer, who takes in your design guidelines and creates an application for you. A common workflow with v0 is putting in design files and images to scaffold your application and then use text prompts to nudge v0 into creating your perfect application. Remember, just like any other AI tool, the quality of the output that v0 generates depends on the quality of the prompt or instructions you input. So, it’s important to be clear, descripti…

Hi @dowidubai2-9714, welcome to the Vercel Community!

Sorry that you are facing this issue. Can you check project settings and ensure that the v0 project is linked to a Vercel project?

If possible can you try logging into a private browser window to ensure there’s no cache issues on v0.

Hi @AnshumanBhardwaj, thanks for the clarification above.

I’m experiencing exactly the same issue.

• Tested in both personal and team workspaces

  • Personal: “Private” & “Anyone with the link” → error
  • Team: “Share” & “Anyone with the link” → error

• Tried across multiple projects, same error each time

• Publishing to the web works fine, but for temporary user interviews we really need the old “Anyone with the link” preview in v0 itself.

Actually, during a user interview today, the error occurred and we couldn’t proceed with the test, which was a big problem.

Could you clarify if this is a permanent change in specification or just a temporary bug?
Knowing this would help us explain the situation to our client companies.

Thanks a lot!
