ValueChange Missing Field 'error'

[ChrisTalman]

According to the insert() documentation:

Documents in changes for which an error occurs (such as a key conflict) will have a third field, error, with an explanation of the error.

It seems that ValueChange currently lacks this in the type definitions.

The fix would seem to be very minor: simply add to ValueChange a third optional property, error.

I couldn't reproduce this error field. tried listening to a table that got a conflict error and I got nothing in the "changes" feed...

[ChrisTalman]

I encountered the field during my use of forEach().

To be clear, this is the changes field of an insert() result object.

Found it, returnChanges should be "always" for me to see it.
