Your pull request is open and the project builds locally, but Vercel comments that the Git author must belong to the project team. Start with the deployment's exact message and commit. This access gate can stop a preview before Vercel runs the build, so changing application code or repeatedly asking an agent to rebuild will not address it.
Confirm which gate failed
Open the PR's deployment status and Vercel bot comment. Record the Vercel project and team, the PR head commit, the GitHub account Vercel names, and whether a build log exists for that commit. A failed deployment and a passing GitHub check can coexist: the check may only cover a separate integration, while no usable Preview was created. A local production build confirms code can build on your machine, but it does not grant the commit author access to a Vercel team.
| Evidence | What it means | Next check |
|---|---|---|
| Team access or author membership message before build logs | Vercel is checking who may deploy this commit | Git author, linked Vercel login, destination team |
| Build log contains a compiler or dependency error | The deployment passed the access gate and tried to build | First actionable build error and project settings |
| Preview URL exists but a page or request fails | The build/deployment completed; a runtime path fails | Browser request, function logs, backend target |
Match the commit author to the right Vercel account
For a private repository in a GitHub organization connected to a Vercel Pro team, Vercel says the commit author must be a member of the team that owns the project. It associates the commit author with a Vercel user through Login Connections, then checks membership. Ask the contributor to verify that the GitHub account used for the commit is connected to the intended Vercel account. A GitHub repository collaborator is not automatically a member of the Vercel project team. Record the author of the blocked commit and the project team; do not change Git history merely to impersonate another author.
- A repository owner's successful deployments do not prove every contributor can create previews.
- A PR can be reviewed in GitHub even while its Vercel Preview is blocked.
- Check whether the repository is private, belongs to an organization, and deploys under a Pro or Hobby team before applying a plan-specific rule.
Let the project owner resolve access
If the contributor has a Vercel account with the correct Git connection, the team's collaboration settings may add them or require a team Owner to approve a request. If there is no Vercel account, the contributor needs to create one and link the Git provider first. Vercel documents a different restriction for private organization repositories on Hobby teams: those repositories cannot deploy to a Hobby team; the owner must decide whether a Pro team is appropriate. These are account and team decisions for the owner, not code changes for the coding agent. Do not weaken deployment protection or make a private repository public just to clear a preview unless the owner explicitly chooses that change after reviewing its effect.
- Have the team Owner review the access request and intended project scope.
- If Vercel reports a fork authorization prompt on a public repository, follow that separate fork approval path.
- Keep credentials, invite links, and private team details out of public agent prompts.
Retest the same PR head
After the authorized account or membership correction, check whether Vercel created a new deployment for the same commit. If none appears, ask the project owner to use Vercel's documented deployment controls for the specific Git reference; avoid making a meaningless code commit only to trigger another attempt. Once a Preview URL exists, test the actual page and its important user path. Then inspect the final PR head, deployment commit, and checks before merging. A newly permitted build can still fail for code, environment, or runtime reasons; use the broader Preview guide if it reaches one of those later boundaries.
- Compare the Preview's commit with the current PR head.
- Run one real smoke test on the deployed page, not only a status check.
- Keep the local build result and the hosted deployment result as separate evidence.

Why does Vercel reject my PR when pnpm build passes locally?
The access check can happen before Vercel builds. A local build tests source and dependencies on your machine; it does not prove the commit author can deploy to the connected Vercel team.
Does GitHub repo access grant Vercel team access?
No. For the documented private organization repository path, Vercel checks the author against the team that owns the connected Vercel project through the author's linked login.
Can I fix this by asking the coding agent to change vercel.json?
A team-membership error is an account and project access issue. First verify the author, linked account, plan, and team; edit build configuration only if a later build log identifies a separate configuration error.
Will approval of team access automatically deploy the blocked commit?
Check whether a new deployment appears and which commit it uses. If none appears, the project owner can use Vercel's documented Create Deployment action with the intended Git reference.
