Error uploading air application to Apple

[colinsgrp]

I am getting an error trying to upload an app to the iOS store. 

The application was developed using FlashBuilder 4.7 and Flex 4.11.0.

ERROR ITMS-9000: “No architectures in the binary. Lipo failed to detect any architectures in the bundle executable.” At SoftwareAssets/SoftwareAsset (MZItmspSoftwareAssetPackage)

Does anyone have any ideas as to what this error is?  Any help would be appreciated.

Thanks.

I found my problem there was something configured wrong on the Mac I was using.  Switched to a different Mac and it took the upload.  Not exactly sure what but I think it had something to do with the version of the Application loader and OSX.
