AOT error with ES6 target and not with ES5 (Angular 5)

[Arnaud Deman]

Hi,

I am facing this error when I use 'target':'ES6' in my tsconfig.json.

with ES5 it works.

There is no error during the compilation: ng serve -prod -aot

But this exception is thrown in the browser.

ERROR TypeError: Cannot read property '_moduleDoBootstrap' of undefined

What could be be the right strategy to understand what happens in this kind of case ?

I have migrated my project under angular cli and Angular 5 from  Angular 4 at the same time. This  was not very smart,  there is a lot of changes and I am a little bit lost.

Thanks in advance,

regards,

Arnaud.

Hi Arnaud,

I use as target `es2015` which should be the same as 'es6' but you never know.. 

next thing I always do on large upgrades is `rm -fr node_modules yarn.lock` followed up by a `yarn`  (or npm if you use that, but don't forget to kill the lock file!

Regards

Hi Sander,

Thanks for your advice.

Unfortunatly I have the same error with es2015.

I will try to see if there is a way to narrow the problem, perhaps by disabling some step of aot if it is possible with angular cli.

I wonder if the source of the error could be in the DI as I use InjectionToken with interface. If it's the case, a solution could be to use a  class-interface instead of an interface ?

Thanks for your time,

regards,

Arnaud.
