Production builds failing in ember 3.4.4 | Build Error (UglifyWriter) #49

esbanarango · 2018-09-28T03:10:10Z

Similar to #35. I'm deploying this APP to heroku using the nodejs heroku buildpack

package.json

    "ember-cli-uglify": "^2.1.0",
    "ember-cli": "~3.4.1",
    "ember-source": "3.4.4",

Error details:

ember-cli: 3.4.3
node: 8.12.0
os: linux x64

Environment: production
cleaning up...

Build Error (UglifyWriter)

Cannot read property '_walk' of null

Workaround

module.exports = function(defaults) {
  let app = new EmberApp(defaults, {
    // ...
    'ember-cli-uglify': {
      uglify: {
        compress: false // added this to workaround the issue
      }
    },
    // ...

The text was updated successfully, but these errors were encountered:

Hey, I got a fix for this that got my build back up and running!
ember-cli/ember-cli#8075 (comment)

rwjblue · 2018-09-30T14:12:09Z

We should confirm with the terser folks that this is a known issue...

jrjohnson · 2018-10-01T16:19:15Z

Terser is (understandably) waiting for a minimal reproduction terser/terser#120 I have no idea how to produce that.

ryanto · 2019-01-04T02:29:55Z

Heya! We just ran into this issue today while upgrading our app. Is compress: false still the best way to fix this?

donaldsonjulia · 2019-02-07T21:29:29Z

This appears to have been fixed by Terser. I was able to remove the workaround from our config after updating ember-cli-uglify to 2.1.0. App builds fine now.

(As a note, we recently discovered that the workaround caused an issue with our app's ability to run in IE11. Updating version and removing the workaround fixed that problem.)

rwjblue · 2019-02-28T23:14:55Z

Awesome, thank you @donaldsonjulia!

udhayakumargururaj · 2019-05-05T05:59:18Z

@donaldsonjulia - getting JS heap out of memory error on production build. when we upgrade ember-cli-uglify to 2.1.0 or 3.0.0

edipox · 2020-06-10T19:03:52Z

In my case I got:

Build Error (UglifyWriter)
Unexpected token: eof (undefined)

The solution was to update ember-cli-moment-shim to version v3.8.0

betocantu93 · 2020-06-11T17:11:17Z

@edipox I'm glad the dep update has fixed your build, I just updated ember-cli-moment-shim, but we're still having issues, would you mind sharing how you came up with that exact dep?

My error is:

Build Error (UglifyWriter)

Unexpected token: punc (.)

Thanks in advance

jrjohnson · 2020-06-11T19:28:49Z

@betocantu93 discovering this issue is a bit of an involved process with two possible paths.

Do a git-bisect from a working build and try and figure out exactly what update causes the failure. Then add that addon to a fresh ember app and see if the issue is resolved.
Produce an app.js file by running your ember build with uglify disabled:

var app = new EmberApp({
  'ember-cli-uglify': {
    enabled: true,
  },
});

ember build -e=production

Then you can take that file and run it through terser manually dist/assets/app.js -c sequences=30` and see if you can spot the failure.

Last time I ended up going chunk by chunk deleting things from that app.js file until I found the broken bit.

I haven't found an easier path, maybe someone else has?

betocantu93 · 2020-06-29T23:49:34Z

Documenting my journey, I did what @jrjohnson suggested and here are my findings

Optional chaining is not yet supported by terser.js Nullish coalescing / optional chaining support terser/terser#567, in the end was a targets.js version issue for optional-chaining I had to use last 2 Chrome versions to fix it, instead of last 1 Chrome versions, you can find more info here: https://discord.com/channels/480462759797063690/485861149821239298/725725873851990066
As @edipox suggested, ember-cli-moment-shim needs to be updated to 3.8.0

Thanks both for answering/documenting

EvgenyOrekhov · 2020-08-31T15:08:00Z

@betocantu93 You saved my day. The only thing is that using last 2 Chrome versions doesn't work anymore (time flies), I had to use Chrome 79 (optional chaining was added in Chrome 80).

betocantu93 · 2020-08-31T16:29:04Z

@EvgenyOrekhov yes, I think I end up doing just that a couple of days later when the build started to fail again, I pinned the Chrome version to a safe one until terser catches up

rami-alloush · 2022-10-25T06:43:05Z

Nothing worked for me. I ended up completely removing ember-cli-uglify and using ember-cli-terser

nikasulo · 2024-11-25T11:44:09Z

Recently ran into this issue and ended up replacing ember-cli-uglify with using ember-cli-terser. Thanks for saving me hours @rami-alloush
