Is this a regression?

Yes, the previous version in which this bug was not present was 8.2.1, maybe 8.2.2

Description

When using ng build in circle ci, it throws an error (screenshot attached):

Generating ES5 bundles for differential loading...
An unhandled exception occurred: cancel after 1 retries!

🔬 Minimal Reproduction

Unfortunately, I cant provide a way to reproduce it as it happens only in CI and I am unable to get the logs. I think it's related to the size of my app but I cant be sure.

Same issue here.

Hi @ronfogel and @xawill, can anyone of you provide the logs please and take it from there?

Most likely though we'd need a minimal repro.

You can read here why this is needed. A good way to make a minimal repro is to create a new app via ng new repro-app and adding the minimum possible code to show the problem. Then you can push this repository to github and link it here.

Dear @alan-agius4,

Thank you very much for getting back to us so quickly. Here are my logs :

As a programmer, I totally understand why you need a way to reproduce the problem in order to solve it. Unfortunately I cannot, as it only happens when building in the CI (i.e. it doesn't happen locally even though the setup is identical) and of course I cannot give you access to my CI...

I have no clue how to help you help me for this one... But tell me if you have any idea.

Seeing the full stacktrace it might be a resource problem since CIRCLE CI will have limited resources If you are using the free plan the resources are 2CPU and 4096MB.
