I got the same error w/ version 1.2.5

But my package.json is like this:

"config": {
"ionic_rollup": "./config/rollup.config.js",
"ionic_generate_source_map": true,
"ionic_bundler": "rollup"
},

[kleeb]

the same for me on rollup
using version 1.2.5, ionic 3.0_beta3, TS 2.2.2

I JSON.stringified the object, as I guess everyone has slightly different problem there, which always ends up with [object Object] and received:

{"taskModule":"uglifyjs","taskWorker":"uglifyjsWorker","reject":{"message":"ENOENT: no such file or directory, open 'www/build/raven.min.js.map'","name":"Error","stack":"Error: ENOENT: no such file or directory, open 'www/build/raven.min.js.map'\n    at new BuildError (node_modules/@ionic/app-scripts/dist/util/errors.js:16:28)\n    at taskReject (node_modules/@ionic/app-scripts/dist/worker-process.js:36:22)\n    at node_modules/@ionic/app-scripts/dist/worker-process.js:14:13\n    at process._tickCallback (internal/process/next_tick.js:103:7)","hasBeenLogged":false,"isFatal":false},"pid":37891}

which clearly says that I am missing sourcemap for some external js library that we are using
adding sourcemap to copy scripts solved the problem

[danbucholtz]

@kleeb,

Can you give me steps to reproduce?

Thanks,
Dan

[kleeb]

Yes.
Add some external js library (like for instance https://www.npmjs.com/package/raven-js) and add it to copy.config.js in module.exports

  copyRaven: {
    src: ['{{ROOT}}/node_modules/raven-js/dist/raven.min.js'],
    dest: '{{BUILD}}'
  }

not sure if this is enough. If not add it to index.html and add declare var Raven somewhere in the code (like app.component.ts)

[danbucholtz]

Okay, thanks, we'll fix it.

Thanks,
Dan

I am still facing this issue when compiling code with ionic 3.
