The Ag Grid Cell Render feature is not available

I have been working on creating my own cell renderer by referring to this example https://www.ag-grid.com/javascript-data-grid/cell-rendering/, but I am running into an issue when using TypeScript. When I define a class that implements the ICellRenderer interface and try to implement its methods, I encounter a compile time error: "Property 'eGui' does not exist on type 'MessageCellRenderer'."

Below is a snippet from my TypeScript file where I define the renderer along with the view containing the grid. NOTE: The grid functions properly without the cell renderer, but I need to customize the styling of cells based on their values, hence why I am trying to utilize the cell renderer.

import {ErrorFilterView} from "./error-dialog/error-filter-view";
import {ICellRenderer} from 'ag-grid-community/main';

var agGrid = require('../../../../node_modules/ag-grid-community');

class MessageCellRenderer implements ICellRenderer{
  
  init(params) {
    this.eGui = document.createElement('span');
    if (params.value !== '' || params.value !== undefined) {
      this.eGui.innerHTML = `'<span class="error_read_#: params.value# error-item_#: Id#">#:Message#</span>'`;
    }
  }

   // gets called once when grid ready to insert the element
   public getGui() {
    return this.eGui;
  };

  // gets called whenever the user gets the cell to refresh
   public refresh(params) {
     // set value into cell again
     this.eValue.innerHTML = params.value;
   };

 // gets called when the cell is removed from the grid
 public destroy() {
   // do cleanup, remove event listener from button

  };
}

export var NotificationsDialogView = (viewModel : ErrorDialogViewModel) => {
  if (!viewModel.getIsInitialized()) return;

  var messageGrid: any;
  var config = (element : any, isInitialized : boolean, context : any) => {

    mdlInit(element, isInitialized, context);

Resolved the issue by including necessary variable definitions since the example was based on JavaScript, while TypeScript is a more strongly typed language.
