I would like to get a specific item by ID. I'm really stuck how I can retrieve this item.

I called the list and tried to save it in an object and then should in the render() function.

Here is my code so far:

import * as React from 'react';
import styles from './Webpartprojectsw.module.scss';
import { ISolypListItemState } from './ISolypListItemState';
import { IWebpartprojectswProps } from './IWebpartprojectswProps';
import { escape } from '@microsoft/sp-lodash-subset';
import * as jquery from 'jquery';
import { TextField, PrimaryButton } from '@fluentui/react';
import {ISPHttpClientOptions, SPHttpClient,SPHttpClientResponse} from '@microsoft/sp-http';
import { ISolypListItem } from './ISolypListItem';

  export default class Webpartprojectsw extends 
React.Component<IWebpartprojectswProps,ISolypListItemState> {

static websiteurl: string="";
public constructor(props:IWebpartprojectswProps, state: ISolypListItemState){
           Id: 0,
           Title: "",


 public componentDidMount(): void {
   let reactcontexthandler = this;
   console.log("Link zur Seite:" + Webpartprojectsw.websiteurl);
        type: "GET",
        headers: {'Accept':'application/json;odata=verbose;'},
        success: function (resultData){
          SolypProjectItem: resultData.d.results[0]
        error: function (jqXHR,textStatus,errorThrown){




public render(): React.ReactElement<IWebpartprojectswProps> {
return (


Here is my interface:

export interface ISolypListItem{
Id: number;
Title: string;
StartDate: string;
EndDate: string;
ProjectPhase: string;
TrafficLight: string;

and my State:

import { ISolypListItem } from "./ISolypListItem";

export interface ISolypListItemState{
   status: string;
  SolypProjectItems: ISolypListItem[];
  SolypProjectItem: ISolypListItem;

I don't exactly how I can put the retrieved element into the object and then use in the HTML.

  • Are you getting correct results in success function of ajax call? Commented Jun 4, 2022 at 7:16

When you are fetching a specific list item using items(<item-id>) endpoint you get the results in resultData.d instead of resultData.d.results.

For Example:

enter image description here

So, change your success function like this:

success: function (resultData) {
                 SolypProjectItem: resultData.d
  • That's great! I try to use this.

  • No, I get an error message that says that My variable is undefined:Cannot read properties of undefined (reading 'Id'). Do you have an idea where it is coming from?

  • Are you getting correct results in resultData variable? check by adding console.log(resultData). Commented Jun 6, 2022 at 8:58
