I was working along on quizzes, and I getting the error on my iPhone (testing device): "The configuration data for this application is invalid". So far I have tried 1) to copy the latest config file into Xcode, 2) checking to see if the JSON is valid (it is), 3) searching my quiz questions for parentheses that could be confusing the JSON file, and 4) turned everything off and reopened Xcode. No luck so far. What ideas do you have? What else can I try?

* Delete the app from your phone and reinstall * Run the app in Xcode and see what shows up in the debug console when the error comes up Mark

Look for question marks, parenthesis (as you have) and any other type of punctuation. Also, make sure that your quotes aren't smart quotes. That stumped me at first as well. One thing I did until I figured out the punctuation marks was to feed it in one at a time until the problem presented itself. Cheryl

Watching the debug console will show you when a special character issue comes up! Mark

Thanks for the responses overnight, Cheryl and Mark! But we can use question marks in quizzes, right? I saw one post where someone had this problem when they inadvertently had an extra space before the question mark. I think the problem definitely is a problem with punctuation in the quiz. Here are my errors: "Error Domain=org.brautaset.JSON.ErrorDomain Code=5 \"Unescaped control character '0xa'\" UserInfo=0x4616e0 {NSLocalizedDescription=Unescaped control character '0xa'}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 \"Object value expected for key: questionText\" UserInfo=0x4617b0 {NSUnderlyingError=0x461720 \"Unescaped control character '0xa'\", NSLocalizedDescription=Object value expected for key: questionText}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 \"Expected value while parsing array\" UserInfo=0x4617f0 {NSUnderlyingError=0x461790 \"Object value expected for key: questionText\", NSLocalizedDescription=Expected value while parsing array}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 \"Object value expected for key: childItems\" UserInfo=0x4618c0 {NSUnderlyingError=0x461880 \"Expected value while parsing array\", NSLocalizedDescription=Object value expected for key: childItems}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 \"Expected value while parsing array\" UserInfo=0x461910 {NSUnderlyingError=0x4618a0 \"Object value expected for key: childItems\", NSLocalizedDescription=Expected value while parsing array}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 \"Object value expected for key: BT_screens\" UserInfo=0x461a00 {NSUnderlyingError=0x4619a0 \"Expected value while parsing array\", NSLocalizedDescription=Object value expected for key: BT_screens}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 \"Expected value while parsing array\" UserInfo=0x461a40 {NSUnderlyingError=0x4619e0 \"Object value expected for key: BT_screens\", NSLocalizedDescription=Expected value while parsing array}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 \"Object value expected for key: BT_items\" UserInfo=0x461b10 {NSUnderlyingError=0x461ad0 \"Expected value while parsing array\", NSLocalizedDescription=Object value expected for key: BT_items}", "Error Domain=org.brautaset.JSON.ErrorDomain Code=3 \"Object value expected for key: BT_appConfig\" UserInfo=0x461bd0 {NSUnderlyingError=0x461af0 \"Object value expected for key: BT_items\", NSLocalizedDescription=Object value expected for key: BT_appConfig}" )

I found it. The problem was my use of apostrophes. I took them out, and now it works. There is a workaround for this--I remember this from a couple years ago. I will see if I can find it and post it.

For future reference remember that the JSON validator tool will always pin point those thypes of errors in mili-seconds: http://jsonlint.com Glad you found the error though :) !
