Binding { type: 'once', ... } fires Query.off which returns an error

[DeividasK]

Hi there!

I get an error after binding the data once, like this:

@firebaseConnect((props) => ([
  { type: 'once', path: DH.getUserProfile(props.uid) },
  { type: 'once', path: DH.getUserGoalsPath(props.uid) },
]))

Below is the error I get:

database.js:130 Uncaught Error: Query.off failed: first argument must be a valid event type: "value", "child_added", "child_removed", "child_changed", or "child_moved".

I figure this is because 'once' does not have any watchers which should be unset. However, couldn't find a fix in the code. Would appreciate your help on this one!

Just to confirm I get the reproduction of the problem right, which version are you using?

[DeividasK]

v1.1.5

[prescottprue]

Try v1.2.0-rc.2 and see if it fixes it for you. It skips calling off for once

Fix works.

Great to hear! Planning on releasing v1.2.0 in a few minutes (which will include this fix).
