Confused about row(key).exists()

[briangruber]

I'm confused about using the exists() method on a row(key), hoping to get clarification.
If I want to check if a row exists I thought I would do this

table.row(key).exists().then(result => {
  let exists = result[0]
}

If the row does exists then I do step into the .then and exists will be true. But if it doesn't exist I actually get an exception of Unknown row: key. So, then what is the point of exists if when it doesn't exist it throws an error? Is result[0] expected to always be true and if it doesn't exist I'm supposed to use the exception? Or am I missing something?

Thanks!

Sounds like a bug! Just to confirm - are you reporting this for the Bigtable client?

[briangruber]

Yes, this is for the node module @google-cloud/bigtable
