Angular 8 project compiled error in production

Question

I have a project in Angular version 8.2.14 and it works without errors. However, when I compile it in production and upload it to the server, it returns the following error for which I cannot find out the reason.

I've searched for errors related to NullInjectorError: StaticInjectorError, but I can't find a solution to this specific problem.

ERROR Error: Uncaught (in promise): NullInjectorError: StaticInjectorError(Hl)[Hv -> e]: 
  StaticInjectorError(Platform: core)[Hv -> e]: 
    NullInjectorError: No provider for e!
NullInjectorError: StaticInjectorError(Hl)[Hv -> e]:

However, if I compile the project in development and upload it to the server, it works perfectly.

I have tried to search for the problem but I can't find it. Another option would be to change the version of Angular but the project is quite large and I don't want to do the long work so that it keeps giving me the same error without knowing the reason.
