Cannot use a Response.json return as a variable to build in Nextjs 15.3.2

Link to the code that reproduces this issue

https://github.com/dqfort/nextjs-build-error

To Reproduce

1. Create a ts file including this code:

export const ErrorResponse = (statusCode: number, message: string) => {
  return Response.json({
    message
  }, {
    status: statusCode
  });
}

export const unknownError = ErrorResponse(520, "Unknown error.");

2. Import the file in the project to use the variable.
3. Run npm run build, but it will fail.

Additional context

I tested it worked for this dependecies:

"next": "15.0.3",
"react": "^18.1.0",
"react-dom": "^18.0.0"

but not work for this dependecies:

"react": "^19.0.0",
"react-dom": "^19.0.0",
"next": "15.3.2"

I just took a look at this and it appears that the compiled page is not using the renamed message variable and wanted to add some additional information.

The following code from lib/common/http.ts:

export const ErrorResponse = (statusCode: number, message: string) => {
    return Response.json({
        message
    }, {
        status: statusCode
    });
}

Gets compiled into the page (.next/server/app/test/page.js) like this:

9726:(e,t,r)=>{"use strict";r.r(t),r.d(t,{default:()=>o});var s=r(687);Response.json({message},{status:520})

When changing the message line to message: message, the build works and it's compiled like this:

9726:(e,t,r)=>{"use strict";r.r(t),r.d(t,{default:()=>o});var s=r(687);Response.json({message:"Unknown error."},{status:520})

So it looks like the build process is incorrectly processing the message var during compilation. Also checked against Next.js 15.4.0-canary.35 and the issue is still present.

Perhaps also worth noting that this error does not happen with the original code using the experimental turbo compiler.

let s=(t,e)=>Response.json({message:e},{status:t}),r=s(520,"Unknown error.")
