Code Signing - Xojo 2019

I recently wrote a simple code-sign/package app in Swift, works fine for Swift apps, and “most” Xojo apps. But I tried on today and it fails

codesign --sign 'Developer ID Application: R.David Sisemore (XXXX)'  --timestamp --force --options runtime '/Volumes/myApp.app/Contents/MacOS/myApp'

A=/'/Volumes/myApp.app/Contents/MacOS/myApp/Contents/MacOSmyAopp: resource fork, Finder information, or similar detritus not allowed

xattr -rc ''/Volumes/myApp.app/Contents/MacOS/myApp''

But it doesn’t remove it… I think it might be due to the fact this app contains 40+ PNG files

Any ideas?

all terminal commands say there is NOTHING there…

I ran that XATTR command manually several type and it finally cleared the issue.
