Hi, I’m encountering a blocking issue when trying to use v0 by Vercel for site generation.

Current Behavior:

• Upon page load, I get this error in the console:

1
NODE_ENV cannot be accessed on the client.
2
Failed to initialize v0: Failed to register a ServiceWorker for scope ('https://kzmlj78x5nizg9wcg9yh.lite.vusercontent.net/') with script ('https://kzmlj78x5nizg9wcg9yh.lite.vusercontent.net/__v0_sw.js'): Operation has been aborted

Expected Behavior:

• v0 should initialize and allow preview or generation as usual.
• No ServiceWorker-related errors, and environment variables (NODE_ENV) should be properly scoped.

Steps to Reproduce:

1. Open v0 by Vercel
2. Start editing or generating a new site
3. Observe the developer console

Notes:

• This issue seems to be related to __v0_sw.js not registering.
• Possibly a regression from a recent update?

Any insight or workaround would be greatly appreciated. Let me know if logs or more details are needed!

Thanks in advance.

hi,

1. the NODE_ENV issue means the code v0 generated (or that you provided) is being fetched on the client-side of your code
2. The service worker is a separate issue that should not impair functionality

Can you share more specifics about the actual problems you are seeing?
