Vercel deployment failure with internal error during deploying outputs phase

[yashank-d]

Problem

I am experiencing a deployment failure on Vercel even though the build completes successfully.

Current Behavior

The failure occurs during the “Deploying outputs” phase with the following message:

Error: We encountered an internal error. Please try again.

The build logs show:

Next.js 16.1.6
Build completed successfully
Static files collected
Serverless functions created
Output generated in /vercel/output

There are no build errors, no runtime errors, and no TypeScript errors. The issue happens after the build phase finishes.

Expected Behavior

Deployment should complete successfully since the build phase finishes without errors.

Environment

• Framework: Next.js 16.1.6
• Router: App Router
• Deployment target: Production
• Runtime: Node.js
• Features: Using serverless functions, no edge middleware errors, no custom build output configuration.

This appears to be an internal deployment infrastructure issue rather than a build or configuration problem.

“Deployments with Middleware Functions are also impacted, because Middleware Functions are deployed globally for production deployments.”

encountering same error here. builds fine, just this error at the end during deployment.
Does this have anything with do with the middle-east war going on? (Dubai region service interrupted) My application is in the Asia-pacific though.

“Error: We encountered an internal error. Please try again.”

Same; builds correctly, says it’s “Deploying outputs..” then gives me “Error: We encountered an internal error. Please try again.”
