[Vuejs]-Vuefire Firebase update issues

According to this post,

When you pass an object to Firebase, the values of the properties can
be a value or null (in which case the property will be removed). They
can not be undefined, which is what you’re passing in according to the
error.

Your error message suggests that post.video‘s value is undefined. You can use logical-or to provide a fallback value like so:

  video: post.video || null,

That means whenever post.video has a false-y value, the expression will evaluate to null. That could catch empty string or numeric 0, though. To be more precisely correct, you should use

  video: typeof post.video === 'undefined' ? null : post.video,

If you need to do this check for many values, you can write a function for it:

function nullIfUndefined(value) {
  return typeof value === 'undefined' ? null : value;
}

then your expression would just be

  video: nullIfUndefined(post.video),
