Angular 8 error “Expected 2-3 arguments, but got 1”

I am learning Angular and I have this scenario in one of my services

agree(id: string) {
    const headers = new HttpHeaders('Content-Type: application/json'); 
    return this.HttpClient.put(`${this.apiUrl}/agree/`, JSON.stringify(id), {headers});
  }

This approach worked without issues as expected...but I realized that to pass the userId is not a Best Practice, instead I use the HttpContext.User to take user Id property on my ASP.Net Core Web API, so I changed my method.

agree() {
    return this.HttpClient.put(`${this.apiUrl}/agreeEula/`);
  }

Now I have this issue

“Expected 2-3 arguments, but got 1”

I will appreciate any suggestion, Thanks in advance

This is the signature for HttpClient.put

put(url: string, body: any, options: { headers?: HttpHeaders | { [header: string]: string | string[]; }; observe?: "body"; params?: HttpParams | { [param: string]: string | string[]; }; reportProgress?: boolean; responseType: "arraybuffer"; withCredentials?: boolean; }): Observable<ArrayBuffer>

In case the body in optional, you can pass {} or null as the second argument after the url.

You need to put null or {} for the 2nd parameter.

agree() {
  return this.HttpClient.put(`${this.apiUrl}/agreeEula/`, null);
}
