fastlane cannot export ipa - ios

Question

My project is using Automatically managing signing
When I want to use fastlane to export ipa, I got following error
I could find archive file in Xcode's Organizer window
but could not export to ipa file
Is there something I didn't notice?

lane :CIUAT do
gym(scheme: "MyApp",
clean: true,
export_method: "development",
output_name: "MyApp.ipa",
xcargs: "-allowProvisioningUpdates",
include_symbols: true,
include_bitcode: false
)
end

Answer 1

You export method is set to development it should be set for AppStore if you want to upload on AppStore and if you want distribute app for testing only then it should be set to AdHoc
change export method to:
export_method: "app-store"
and provide provisional profiles
