2 TypeError: Cannot read properties of undefined (reading 'value') in reactjs with event handler

Question

What's the issue with my code ?

I've gotten two - TypeError: Cannot read properties of undefined (reading 'value')

expected behavior = click one button, the button uses class name red and calls function addValue if I click this button again it should call function removeValue and its color should change to white.

Instead I get this type error and every button is highlighted in red.

const [color, setColor] = useState(false)



function addValue(e) {
> 38 |     if (e.target.value !== "") {

  function removeValue(e, value) {
> 63 |   if (e.target.value !== "") {

These are the functions

function addValue(e) {
    if (e.target.value !== "") {
      
      if (!favs.includes(e.target.value)) {
        favs.push(e.target.value);
        localStorage.setItem("name", JSON.stringify(favs));
        console.log(favs);
        document.getElementById("favsarray").innerHTML =  favs
      }
    }
  }



function removeValue(e, value) {
    if (e.target.value !== "") {
      //delete from array
      favs.pop(e.target.value);
      console.log(favs);
      //change the div text
      document.getElementById("favsarray").innerHTML = favs;
      //get the values from localstorage- parse
      const stored = JSON.parse(localStorage.getItem("name"));
      //delete the value
      delete stored[(value, e.target.value)];
      //store the new array as a string
      localStorage.setItem("name", JSON.stringify(favs));
      console.log(stored);
    }
  }

I am calling this function with this and an event handler

function addOrRemove(e) {
  const elem = e.currentTarget;
  setColor(!color)
if (color){
  addValue(elem)
} else {
  removeValue(elem)
}
}


<button
                id="btn"
                onClick={addOrRemove}
                className={color? "white": "red"}
                value={"Name:  " + d.name + "  Description:   " + d.description + "  Stars: " + d.stargazers_count + "  URL:   " + d.html_url}
