upload new build to same version using fastlane?

Issue

I have an existing app and want to use Fastlane so after adding some configuration I want to send the new build to testflight,

so I use this lane

platform :ios do
   
    private_lane :staging_build do
        increment_build_number(xcodeproj: './ios/myapp.xcodeproj')
        gym(scheme: 'myApp', workspace: './ios/myapp.xcworkspace')
    end

   
    desc 'Build & send to testflight'
    lane :upload_to_testF do
        staging_build
        upload_to_testflight(username: '*****@gmail.com', app_identifier: 'com.comp.myapp')
        commit_version_bump(message: 'bump build')
        push_to_git_remote
    end 

end

So after run fastlane ios send_to_testF

.ipa file generated and build number increment

I got this error after all

ERROR ITMS-90186: "Invalid Pre-Release Train. The train version '1.0.14' is closed for new build submissions"
ERROR ITMS-90062: "This bundle is invalid. The value for key CFBundleShortVersionString [1.0.14] in the Info.plist file must contain a higher version than that of the previously approved version [1.0.14]. Please find more information about CFBundleShortVersionString at https://developer.apple.com/documentation/bundleresources/information_property_list/cfbundleshortversionstring"

I have this version in the app store

and here's the same in Xcode

so why do they ask to increment it! even I just try and incremented it to 1.0.15 in both code & app store but still got the same error!

Solution

Apple connect wont accept new release with the same version number, but you can let fastlane handle that to ensure you wont miss something. Use something like:

...
increment_version_number(
  version_number: "1.0.15" # Set a specific version number
)
