Typescript is not used. Why am I getting this error? It does not occur in any other component. I have looked at the answers of other questioners but have not found any useful information. Can someone please help me?

The corresponding errors occur at the constructor function location, the shouldComponentUpdate function location, and the render function location.

const RowTextarea = () => {
  constructor(props){
    super(props);
    this.textArea = null;
  }
  shouldComponentUpdate(nextProps){
    if(this.props.input.value !== nextProps.input.value){
      if(isEmpty(nextProps.input.value)){
        this.textArea.setAttribute('rows', this.props.rows);
      }else{
        this.textArea.setAttribute('rows', this.props.rows);
        while(this.textArea.scrollHeight > this.textArea.offsetHeight){
          const tempRows = Number(this.textArea.getAttribute('rows'));
          this.textArea.setAttribute('rows', tempRows + 1);
        }
      }
    }
  }
  return true;
};
