flutterflow -- app help

I have a 100% fully functional app in flutterflow. it works perfectly on both ios and android during testing. When i submit either with xcode or compiled and uploaded with transport I get no errors, but i will eventually get an error "invalid binary" from the App Store Connect from Apple. I get no other errors or emails, and there is no build errors either. looking for someone to help me with this.

I do not have any custom code, and it only has 1 REST API call to a HTTPs site and a webview on another page. I'm not sharing my login, so will need to be through screenshare.
