未捕获的类型错误：无法读取未定义的属性（读取“设置”）

Question

Can anybody help me out with why my browser's console is showing this error when I hit:

Object.getOwnPropertyDescriptor(HTMLElement.prototype, "innerHTML").set;

Actually, I need access to the span tag to update the text but I'm blocked due to an error:

Uncaught TypeError: Cannot read properties of undefined (reading 'set')

The actual code for which I need a solution with span tag is below:

var nativeInputValueSetter = Object.getOwnPropertyDescriptor(window.HTMLInputElement.prototype, "value").set;
nativeInputValueSetter.call(input, 'react 16 value');

var ev2 = new Event('input', { bubbles: true});
input.dispatchEvent(ev2);

that's not the right way to tickle with DOM, try to use ways like accessing elements with querySelector (it's just one way you can do). it can be something like this:

document.querySelector('#related-id').innerText = 'replacing text'
