Problems debugging errors during build #9707

Closed kmcaloon closed 4 years ago

kmcaloon commented 4 years ago

So I am having a couple bugs/issues.

For this, all pages when running in dev are compiling ok. I am getting build errors telling me that a variable is not defined but doesn't specify where exactly.

Here is the error I am getting running next build with target: severless:

> Build error occurred
ReferenceError: propTypes is not defined
    at Object.e0hG (/Applications/MAMP/htdocs/dartdrones.com-next/.next/serverless/pages/[slug].js:7740:11)
    at __webpack_require__ (/Applications/MAMP/htdocs/dartdrones.com-next/.next/serverless/pages/[slug].js:23:31)

    at Object.<anonymous> (/Applications/MAMP/htdocs/dartdrones.com-next/.next/serverless/pages/[slug].js:94:10)
error Command failed with exit code 1.

The thing is, it doesn't really specify where exactly the undefined variable is in my actual code.

For what it's worth, here is my actual [slug].js code:

import React from 'react';

const Demo = () => (

  <div>
    <h1>Slug</h1>
  </div>

);

export default Demo

Here is the error I am getting running next build without the serverless option:

Is there any way I can improve these messages for better debugging?
