White screen after update from deploy

Hi everyone,

Since 2-3 days, I’m not able to deploy any update (no major update, only text and several line of code added). My application still with a white screen (build with angular 5.2.0).

I just read that there is an update angular 6.0.0 since several days but I don’t want to modify all dependency to adapt on this new version.

Anybody with the same problem but with a solution to continue with angular 5.2.0 ?

What does this mean?

Sorry, my English is not good.

“Several lines of code added”
