Having more than one condition in getDerivedStateFromProps in React

In my React application, I have the following code.

state = {
   credentialDeletion: false,
   accountDeletion: false
}

static getDerivedStateFromProps(nextProps) {
   if (nextProps.accountDeleting) {
      return {
         accountDeletion: true
      }
   }

   if (nextProps.credentialDeletion) {
      return {
         credentialDeletion: true
      }
   }

   return null;
}

But this code doesn't work properly. If I remove one condition, then the other works fine. But together, only the first condition works. How should I write this code properly?

You could create an object that you add properties to in each if statement and return that, so that both if statements will be run.

static getDerivedStateFromProps(nextProps) {
  const update = {};

  if (nextProps.accountDeleting) {
    update.accountDeletion = true;
  }
  if (nextProps.credentialDeletion) {
    update.credentialDeletion = true;
  }

  return update;
}
