Instruments exited with code 253 on SauceLabs

Hey there…
I am attempting to set up using Appium with a Cloud Provider (Sauce Labs) and I am getting the following message while initiating the test:

(UIKitApplication:com.ClarizenInt.Clarizen[0x8c18][869]): Program specified by service does not contain one of the requested architectures: �,�
2015-03-26 08:44:54:001 - info: [IOS_SYSLOG_ROW ] Mar 26 01:44:54 SpringBoard[823]: Application 'UIKitApplication:com.ClarizenInt.Clarizen[0x8c18]' exited voluntarily.
2015-03-26 08:44:54:508 - info: [debug] [INST STDERR] Instruments Trace Error : Target failed to run: Failed looking up pid of launched process
2015-03-26 08:44:54:535 - info: [debug] [INSTSERVER] Instruments exited with code 253

Is it because my iOS app is not compiled correctly? Anybody has a clue?
Cheers, Pavel

Just in case anybody runs into this issue:
I mistakenly tried to run the zipped .app folder of the app for the test instead of the .ipa file.
Always make sure that you use the .ipa file for the SauceLabs test

I also get this code but I was launching on local server, with the path to an .ipa file.
