Hi, I have a question regarding angular httpClient.
I have some code below, it throws an error for me: 
Property 'httpClient' does not exist on type 'DocService'.ts
 createObservable(JsonUrl): Observable<any[]> {
    return this.httpClient.get<any[]>(this.baseBatchURL + "getResults", {
      params: JsonUrl,
    });
}
 getValidationData(): Observable<any> {
        return this.createObservable(JsonUrl);
    }
JsonUrl is passing a json file.
Any inputs are welcome.Thanks

httpClient doesn't exist in angular

Angular is a JavaScript open-source web application framework used to develop single-page applications. It aims to simplify both the development and the testing of such applications by providing a framework for client-side model–view–controller (MVC) and model–view–view-model (MVVM) architectures, along with components commonly used in rich Internet applications. Angular is the front-end part of the MEAN stack, together with Node.js runtime, Express.js backend framework and MongoDB database.

JavaScript Object Notation, or JSON, is human-readable text used when transmitting data objects consisting of attribute:value pairs between a server and a web application as an alternative to XML. JSON, while it is originally derived from JavaScript, is a language-independent data format. Code for parsing and generating JSON data is available in many programming languages.
