Debugging the error

Look at the parameter that throws the error and all uses of the class. This error is commonly thrown when a constructor defines parameters with primitive types like string, number, boolean, and Object.

Use the @Injectable method or @Inject decorator from @angular/core to ensure that the type you are injecting is reified (has a runtime representation). Make sure to add a provider to this decorator so that you do not throw NG0201: No Provider Found.
