ipa upload errors

Question

Hi all,
I have been getting errors every time I try uploading my .ipa build file to Transporter. I can't seem to figure out what the issue is.
Here are the 2 errors:

Asset validation failed (90035)
Invalid Signature. Code object is not signed at all. The file at path “Runner.app/Frameworks/serious_python_darwin.framework/python-stdlib/ctypes/macholib/fetch_macholib” is not properly signed. 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). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. 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/support/code-signing. (ID: 38b1e636-0b6f-4379-b746-876495b9ebd4)

Asset validation failed (90208)
Invalid Bundle. The bundle Runner.app/Frameworks/_asyncio.framework does not support the minimum OS Version specified in the Info.plist. (ID: 8b380f23-d42a-4b59-bfec-d39f6fe4604e)

And for reference here is my project.toml:

[project]
name = "XYZ"
version = "1.0.0"
description = "XYZ App"
authors = [{ name = "John Doe", email = "xyz@xyz.com" }]
dependencies = ["flet"]

[tool.flet]
project = "XYZ"
description = "XYZ App"
product = "XYZ"
org = "com.Company"
company = "Company LLC"
copyright = "© 2025 Company LLC"

compile.app = true      # --compile-app
compile.packages = true # --compile-packages
compile.cleanup = true  # --cleanup-on-compile

build_number = 1        #! --build-number
build_version = "1.0.0" # --build-version
app.module = "main"     # --module-name

icon.default = "assets/icon.png"

team = "abc123"

[tool.flet.ios]
team = "abc123"

I have uploaded other Apps successful to App Store Connect from xcode on this machine so I know that the auto signing does work correctly. Therefore Im not sure what the error is referring to.
Also, is the app supposed to be renamed to "Runner" by flet?

Flet version: 0.26.0
Flutter version: 3.27.3 • channel stable
Python: 3.12.8
MacOS M3 15.2

Thanks for your help!
