star-wars example doesn't load in browser, shows "Invariant Violation" error in console

[shanecav]

With a fresh clone of relay, then running npm install and npm start from examples/star-wars/, going to http://localhost:3000 displays the following error in the console:

Invariant Violation: RelayOSSNodeInterface: Expected payload for root field factions to be a single non-array result, instead received an array with 1 results.
_markAsRejected @ relay.js:7312

I was able to reproduce the issue.

It seems like when we try to write the payload for ['empire', 'rebels'], the query we have looks like:

factions(names: 'empire') { ... }

I suspect this issue is due to diffRelayQuery splitting off the faction(names: ...) query and not correctly preserving the Array-ness of the argument.

@kassens Are you sure you updated? I've confirmed the fix on latest.

@shanecav thanks for reporting this issue, this is fixed on master :-)

[kassens]

Okay, works for me as well now. Not sure what was going on.

[shanecav]

Perfect, thanks @josephsavona!
