I have two v0 projects (1 & 2) I have been trying to deploying for the past ten days. They either fail to commit or have some random JSON ‘A’ token error. It’s not getting logged as a failed deployment so I can’t analyze the specific problem.
I upgraded to Vercel Pro again but the projects still wont deploy. All of these errors occurred after the CVE patch earlier in December. I’ve also submitted two support cases and messaged a team member. No responses on how to solve these issues.
It seems like the issue might be related to the deployment configuration or a missing error log. A few things you can try: Check project settings → make sure the Build Command and Output Directory are correct. Try deploying locally with vercel --prod or npm run build to see if any hidden build errors appear. Clear cache and redeploy — sometimes cached builds cause silent failures. If you’re using environment variables, recheck that all required values are added in Vercel dashboard. Create a fresh test project and deploy just to verify if the issue is only with these two v0 projects. If you already tried these, share what the logs show locally — it may help identify where it’s breaking.
Just getting back after the holidays, are you still seeing this issue?
Hey , I wanted to check in and see if you're still experiencing the deployment issues with your v0 projects. Have you found a solution, or do you still need assistance troubleshooting the JSON token error? Let me know if that helps!
