Applescript "Expected end of line but found property." error when using google chrome

I recently updated to OS Mavericks and it appears a few of my applescripts dealing with Google Chrome have stopped working properly.

I have a simple function that opens chrome and creates a new window..

on openWindow()
  tell application "Google Chrome"
      activate
      set newWin to make new window
      tell active tab of newWin to set URL to "http://play.google.com/music"
  end tell
end openWindow

However, this gives me the error: Expected end of line but found property.

referring to the "tab" in "tell active tab of newWin." This link seems to offer a bit of help, but I'm still lost as to how to fix this issue. Can anyone help me get this working again? Thanks.

Solution

  • I'm having a similar problem, also on OS X 10.9.4, where a very simple script

    tell application "iTunes"
    return persistent ID of (first source where kind is library)
end tell

    every now and then returns the exact same error message:

    NSAppleScriptErrorBriefMessage = "Expected end of line but found property.";
NSAppleScriptErrorMessage = "Expected end of line but found property.";
NSAppleScriptErrorNumber = "-2741";
NSAppleScriptErrorRange = "NSRange: {45, 2}";

    It's not a real solution, but in my experience a computer restart gets rid of the issue (for a while). The whole problem looks like a bug in AppleScript to me.

    Turns out I was running a Windows VM using Parallels at the same time. In the VM, there was also an iTunes instance. In essence, I had two different versions of iTunes on the same system. One that understands AppleScript and one that doesn't. Addressing the OS X iTunes like this solved the issue:

    tell application "/Applications/iTunes.app"
    return persistent ID of (first source where kind is library)
end tell

    Perhaps the problem in the original question can be solved the same way.
