JS error from Instruments while using button method

Issues/Bugs
1

OSX 10.10.1, Xcode 6.1.1, Appium 1.3.4, iOS 8.1 iPad 2 simulator, using Ruby

Some of the times when I call button it returns an instruments error on some strings. The buttons are visible, and they appear in the inspector just fine. Here’s some examples

If I call button(“Allow photo access”) it works fine

If I call button(“iPad Case”) I get this error in the appium server log:

info: [debug] Socket data being routed.
info: [debug] Got result from instruments: {"status":17,"value":"undefined is not a function (evaluating 'elementProperty.toLowerCase()')"}
info: [debug] Responding to client with error: {"status":17,"value":{"message":"An error occurred while executing user supplied JavaScript.","origValue":"undefined is not a function (evaluating 'elementProperty.toLowerCase()')"},"sessionId":"33fc2405-4b35-4eeb-a58b-008c792f17db"}

If I call button_exact(“iPad Case”) the method works. Obviously it has something to do with calling .toLowerCase on the string. At first I thought it had something to do with special characters, as I first noticed the error popping up when calling button on a string that had a / within the string, but it seems to happen on some buttons with just letters in the string.

Just some additional info using _by _json as such:

_by_json({typeArray: ["UIAButton"], onlyFirst: true, onlyVisible: true, name:{target: "iPad Case", substring: true, insensitive: true}})

returns the button where button(“iPad Case”) failed

looks like this error is caused by using the current appium_lib from git rather than the gem from rubygems

}

This issue continues to affect me on every button or buttons. And I find very strange that something so big would only affect me.

Any tip on what I might do/change in order to stop this issue from happening to me?

Edit: Just updated ruby to 2.2.0 and reinstalled all gems, etc… and same error :expressionless:
