I had nebular admin panel version 5.0.0 using angular 9 and was working perfectly, I upgraded to version 6.0.0 which uses Angular 10 ( by upgrading the versions in package.json ), now in dev server everything is working perfectly, but after deploying to the production server ( apache on linux ) I get error calling a simple GET request using HttpClient.
TypeError: Object(...) is not a function

I had it working by fixing the imports in httpinterceptor.ts
before
import {Injectable} from '@angular/core';
import {HttpEvent, HttpHandler, HttpInterceptor, HttpRequest} from '@angular/common/http';
import {Observable} from 'rxjs/Observable';
import {catchError} from 'rxjs/operators/catchError';
import { throwError } from 'rxjs/internal/observable/throwError';
after
import {Injectable} from '@angular/core';
import {HttpEvent, HttpHandler, HttpInterceptor, HttpRequest} from '@angular/common/http';
import { Observable, throwError } from 'rxjs';
import { catchError } from 'rxjs/operators';
