Error with Application Loader

When I try to upload my .pkg to the Mac App Store using Application Loader I get the following error:

ERROR ITMS-90239: "Invalid Signature. Code object is not signed at all. The binary at path [PullSticks.app/Contents/MacOS/PullSticks] contains an invalid signature. Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). If you are certain your code signing settings are correct, choose "Clean All" in Xcode, delete the "build" directory in the Finder, and rebuild your release target. For more information, please consult https://developer.apple.com/library...deSigningGuide/Introduction/Introduction.html"

Here are the steps on terminal to codesign the app:

chmod -R a+xr "Unity/Space/MacApp/PullSticks.app"

export CODESIGN_ALLOCATE="/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/codesign_allocate"

codesign --force -v --sign "3rd Party Mac Developer Application: FBF Sistemas" "Unity/Space/MacApp/PullSticks.app/Contents/entitlements.plist"

codesign --force -v --sign "3rd Party Mac Developer Application: FBF Sistemas" --entitlements "Unity/Space/MacApp/PullSticks.app/Contents/entitlements.plist" "Unity/Space/MacApp/PullSticks.app/Contents/Frameworks/MonoEmbedRuntime/osx/libmono.0.dylib"

codesign --force -v --sign "3rd Party Mac Developer Application: FBF Sistemas" --entitlements "Unity/Space/MacApp/PullSticks.app/Contents/entitlements.plist" "Unity/Space/MacApp/PullSticks.app/Contents/Frameworks/MonoEmbedRuntime/osx/libMonoPosixHelper.dylib"

codesign --force --verify --sign "3rd Party Mac Developer Application: FBF Sistemas" --entitlements "Unity/Space/MacApp/PullSticks.app/Contents/entitlements.plist" "Unity/Space/MacApp/PullSticks.app"

productbuild --component "Unity/Space/MacApp/PullSticks.app" "/Applications" --sign "3rd Party Mac Developer Installer: FBF Sistemas" "Unity/Space/MacApp/PullSticks.pkg"

Please, any help?
