Steps to Reproduce the Problem

1. % cat Dockerfile

   FROM python:3
   ADD helloworld.py /
   RUN pip install flask
   RUN pip install flask_restful
   EXPOSE 3000
   CMD [ "python", "./helloworld.py"]

2. % cat helloworld.py

   from flask import Flask, request
   from flask_restful import Resource, Api

   app = Flask(name)
   api = Api(app)

   class Greeting (Resource):
   def get(self):
   return 'Hello World!'

   api.add_resource(Greeting, '/') # Route_1

   if name == 'main':
   app.run('0.0.0.0','3000')

3. To build the image, run
   docker build -t hello-world-python .
   docker-slim build --http-probe=false hello-world-python # tried with http-probe=false

Start with the docker-slim build command and the failure path reported at pkg/app/master/commands/build/handler.go:876, using the provided Python Flask image and Docker/macOS versions to reproduce the unexpected event. Trace the container inspection and start-monitor events in the debug output; done means the image builds successfully or the failure is reported with a clear, actionable cause.
