SOLVED: Ionic 3.4 --prod Error: Internal Error {"reference": null}

saschwarz · June 15, 2017, 6:27pm

I just upgraded to 3.4 and ionic run ios works fine. But when I run ionic run ios --prod I get this cryptic error:

$ ionic cordova run ios --prod
Running app-scripts build: --prod --address 0.0.0.0 --port 8100 --p 8100 --livereload-port 35729 --r 35729 --iscordovaserve --externalIpRequired --nobrowser

I think my install is all up to date:

$ ionic info

global packages:

    @ionic/cli-utils : 1.4.0
    Cordova CLI      : 7.0.1 
    Ionic CLI        : 3.4.0

local packages:

    @ionic/app-scripts              : 1.3.7
    @ionic/cli-plugin-cordova       : 1.4.0
    @ionic/cli-plugin-ionic-angular : 1.3.1
    Cordova Platforms               : android 6.2.3 ios 4.4.0
    Ionic Framework                 : ionic-angular 3.4.0

System:

    Node       : v7.4.0
    OS         : macOS Sierra
    Xcode      : Xcode 8.3.3 Build version 8E3004b 
    ios-deploy : 1.9.1 
    ios-sim    : 5.0.4 
    npm        : 4.0.5

I’d be grateful for any suggestions!

Uh, that’s a strange one.

What does ionic run ios --prod --verbose output?
What does npm run ionic:build --prod --verbose output?

saschwarz · June 15, 2017, 7:10pm

Thanks! I didn’t know about --verbose:

Unfortunately doesn’t tell me much

The compiler doesn’t like something. Unfortunately it doesn’t really tell us what it is.

I ran npm install -g @ionic/cli-plugin-proxy and now it finds that plugin:

If it’s complaining about “static symbols” is that possibly due to the changes in how AOT expects providers to be specified?

saschwarz · June 15, 2017, 7:41pm

I’m putting debugging code in the compiler and walking up the stack to see if I can find the symbol.

Sujan12 · June 15, 2017, 8:41pm

Not neccessary if you don’t use a proxy - the debug message is just voiced a bit “harsh”.

Good luck with the debugging.
Maybe also open an issue with Ionic on Github so the devs are aware.

rapropos · June 15, 2017, 8:47pm

I would be interested in seeing package.json here. I suspect a problem (perhaps in a library) involving DI declarations using tokens.

saschwarz · June 15, 2017, 9:32pm

Just found the problem:

import * as Rollbar from 'rollbar';
...
const providers = [
    ...
        {
            provide: Rollbar,
            useFactory: rollbarFactory
        },
    ...
}

Removing the Rollbar object from the providers solved it. I just need to dig into the reason it worked in early versions of Angular.

rapropos · June 15, 2017, 9:35pm

I would take a look at angular-rollbar.

saschwarz · June 16, 2017, 12:10am

For Angular 4 and the latest rollbar 2.0 package installed via: npm install rollbar --save the solution is to change the import to:

let Rollbar = require('rollbar');

ztp · August 8, 2017, 10:47am

I had the exact same error but on my case the culprit was

import ApolloClient from 'apollo-client';

as seen on GitHunt-Angular

changing it to:

import { ApolloClient } from 'apollo-client';

solved my two days quest.

racedale · October 10, 2017, 6:47pm

I needed to solve this error with Rollbar by using InjectionToken instead, here’s where I found the answer. https://github.com/rollbar/rollbar.js/issues/446
