ElementNotInteractableException

ElementNotInteractableException::
is caused when an element is found, but you can not interact with it. For instance, you may not be able to click or send keys.

There could be several reasons for this:

1. Wait until an element is visible / clickable
WebDriverWait wait = new WebDriverWait(driver, timeout);
wait.until(ExpectedConditions.visibilityOf(element));
wait.until(ExpectedConditions.elementToBeClickable(element));

2. Add Implicit wait

Stale = left over / old

wait.until(ExpectedConditions.visiblityofElementToBeClickable(By.id(“id”)))

wait.until(ExpectedConditions.presenceOfElementLocated(By.id("id")));

wait.until(ExpectedConditions.refreshed(ExpectedConditions.stalenessOf("table")));
