What is causing the error in my Angular application after it is built for production?

My application has completed development. When I run the 'ng build' command, everything runs smoothly. However, when I use the command 

ng build --prod --base-href /Incrency/

The login page appears, but upon attempting to log in, the following error is thrown:

ERROR Error: Uncaught (in promise): Error: No component factory found for t. 
Did you add it to @NgModule.entryComponents?
Error: No component factory found for t. Did you add it to @NgModule.entryComponents?

The versions being used are Angular CLI : 7.3.2, Rxjs : 6.3.3, and Angular Core : 7.0.6

Answer №1

I encountered a similar issue and after attempting various solutions found online, I discovered the problem lied in removing a directive reference from the HTML file. This action resolved the error displayed during ng build, but surfaced again when using the ng build --prod flag. It is important to ensure that the directive actually exists before utilizing it in your HTML code. Hopefully, this insight will help resolve your issue.

Answer №2

One possible issue could be that certain components are being utilized in your application without being declared in NgModule. These components should be included as entryComponents to ensure Angular can properly identify and compile them during the build process.
