Error: PythonPipBuilder:ResolveDependencies

I’m trying to do my first sam build, following tutorial here: https://iwpnd.pw/articles/2020-01/deploy-fastapi-to-aws-lambda#

My application works with fastapi and is working well.

My template.yaml is like this:

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: >

My structure is /Project/app/app/main.py

requirements is in /Project/app template.yaml is in /Project

When I do sam build --use-container --debug after a while I got the following error:
