Amplify Build Failure Due to Missing pip3.9

Question

I'm encountering an issue during the build phase of my AWS Amplify project:

> Starting phase: build
> Executing command: sudo update-alternatives --install /usr/bin/python3 python3 /usr/local/bin/python3.9 11
>
> 2024-04-22T10:27:43.881Z [INFO]: # Executing command: /usr/local/bin/pip3.9 install --user pipenv
>
> 2024-04-22T10:27:43.882Z [WARNING]: /usr/local/bin/pip3.9: No such file or directory
>
> 2024-04-22T10:27:43.883Z [ERROR]: !!! Build failed

Hopefully this provides enough information. Please help!!!
