'OpaqueToken', function calls are not supported

[jogelin]

Version info
Angular: 4.0.0-rc.1
Firebase: 3.6.9
AngularFire: 2.0.0-beta.8
Angular/cli : 1.0.0-rc.0

When I run my app using ng serve, I got this following error :

ERROR in Error encountered resolving symbol values statically. Calling function 'OpaqueToken', function calls are not supported. Consider replacing the function or lambda with a refer
ence to an exported function, resolving symbol FirebaseUserConfig in _path_/node_modules/angularfire2/tokens.d.ts, resolving symbol AngularFireModule.initialize
App in _path_/node_modules/angularfire2/angularfire2.d.ts, resolving symbol AppModule in _path_/src/app/app.module.ts, resolving symbol A
ppModule in *path*/src/app/app.module.ts

If I modify any file which produce a reload of the build, the error disappear and my app works.

I think it's because the OpaqueToken is deprecated in the new Angular 4.x

Hey @jogelin. Angular 4 is still in RC so we're not going to support it until it's in a full release. The fix is simple, but InjectionTokens do not exist in Angular 2.x.

Just upgraded my code base to Angular4, got the below error similar to the above error.

ERROR in Error encountered resolving symbol values statically. Calling function 'OpaqueToken', function calls are not supported. Consider replacing the function or lambda with a reference to an exported function, resolving symbol FirebaseUserConfig in _path/node_modules/angularfire2/tokens.d.ts, resolving symbol AngularFireModule.initializeApp in _path/node_modules/angularfire2/angularfire2.d.ts, resolving symbol AppModule in _path/src/app/app.module.ts, resolving symbol AppModule in _path/ajs/src/app/app.module.ts

Appreciate any help to resolve this.

Just to let you know that I have uninstalled firebase and angularfire2 and reinstalled both which fixed the app working.

npm uninstall firebase angularfire2 --save
npm install firebase angularfire2 --save

@ravivit9 thanks for the hint, reinstalling appears to solve the problem for me as well.

@jogelin yes it is weird. I am running Angular 4.0 now, and gets the same error. Edit any file and recompiles ok.

@davideast Is there a temporary fix for this which I can use?

[LanderBeeuwsaert]

I've reinstalled, but I still get the error. :-/ A temp fix would be much appreciated.

Version info
Angular: 4.0.1
Firebase: 3.7.5
AngularFire: 2.0.0-beta.8
Angular/cli : 1.0.0

Seems that I cannot create a build (to /dist) in an angular-cli project because of this.

I have also reinstalled, but still get the error as well. I'm posting this again because my versions are different:

Version info

This runs locally for me just fine, but Travis CI build fails due to error mention above.

@jakehockey10, just upgraded my code base from 4.0.1 to 4.0.2 as suggested by "ncu" and did ng serve. Now I am also getting the error as stated above.

@jakehockey10, as I posted in one of the above comment. Please do the following to resolve the issue.
npm uninstall firebase angularfire2 --save
npm install firebase angularfire2 --save

It just worked after I uninstalled and installed both firebase and angularfire2. Hope this helps.

[jakehockey10]

@ravivit9, I had already tried what you are suggested and still can't get it to work

[ravivit9]

As I am not sure how Travis build will work. I just managed to make to run in local site only.
