Vercel deployment blocked because commit author does not have contributing access

I am receiving the following error during deployment: Error: Deployment Blocked The Deployment was blocked because the commit author does not have...

Thanks for sharing, Yedidya!

Problem

Hello, I'm the creator of my project but for some reason under Project Settings > Project Members, I'm listed with the Project Role: Project Viewer. Each time I try to deploy, it asks me to upgrade to Pro because I can't have multiple members in one project.

Current Behavior

I am receiving the following error during deployment:

Deployment Blocked: The Deployment was blocked because the commit author does not have contributing access to the project on Vercel. Hobby teams do not support collaboration. Please upgrade to Pro to add team members.

How can I fix this?

Hi everyone,

I’m experiencing a “Deployment Blocked” error on my Hobby project and I’m looking for a way to resolve it.

The Error

Error: The Deployment was blocked because the commit author does not have contributing access to the project on Vercel. Hobby teams do not support collaboration.

The Situation

• I am the sole owner and only member of this project.
• My Vercel account email is verified and set as Primary.
• My local Git configuration (user.email) matches my Vercel account email exactly.
• I’ve verified with git log that the commit author is indeed correct.

What I’ve Already Tried

1. Confirmed that the email is identical on both GitHub and Vercel.
2. Disconnected and reconnected the GitHub repository in the project settings.
3. Attempted to transfer the project, but since it’s a Hobby plan, I’m stuck in the current “Hobby Team” scope.

It appears Vercel is misidentifying me as an external collaborator. Has anyone encountered this false positive before? Is there a way to fix this identity mismatch without upgrading to a Pro plan, given that I am the only person working on this project?

Thanks in advance for your help!

Hey! I moved your original posts to this thread. There's a solution above someone else shared, can you take a look?

hii,

i tried to relinked and still give me error on redploy.

i just have 1 github account linked and its in this vercel account.

Thanks

hii, any solution?

Hey Croquete1, I don’t see any answers yet, so maybe this helps!

Looks like you’re on the Vercel Teams page and you’re the only owner with 2FA on. Since you only have one GitHub account, it’s probably not a team conflict. Most of the time, redeploy errors come from repo permissions or OAuth token issues.

Also, old build data can mess things up sometimes. Try hitting “Redeploy without cache” on the deployment page. If it still fails, take a close look at the deployment logs—they usually tell you if it’s a GitHub auth problem, a permission thing, or just a build failure.

I solved this by simply matching my local Git email/username with the GitHub account connected to the Vercel project.

My system's global Git config (user.name and user.email) was set to a different identity than the GitHub account/repo I was actually pushing to. Vercel checks the commit author's email (not just who has push access), so even though I had full push access to the repo, Vercel treated the commit author as an outsider and blocked the deployment.

Fix:

bash

1
git config --global user.name "your-github-username"
2
git config --global user.email "your-verified-github-email"

(Or run it without --global to set it only for that specific repo.)

Then push a new commit — the deployment goes through fine after that.

Tip: Check git config user.email and compare it against the email shown on your GitHub account's Settings → Emails page. If they don't match, that's likely your issue too.
