API error (404): Could not find the file /opt/dockerslim/artifacts/creport.json in container

Expected Behavior

• Docker-slim should minify a 5GB docker image

Actual Behavior

• level=fatal msg="docker-slim: failure" error="API error (404): Could not find the file /opt/dockerslim/artifacts/creport.json in container c6558fa8fa08e1ccbfd7c28bd23da098788d369fb42e9e57d991bf1bafb1d5eb" stack="goroutine 1

Steps to Reproduce the Problem

1. Grab this docker file, from here
2. Build docker image (standard) docker build -t rembg
3. This will produce a 5.0 GB rembd docker image
4. Invoke docker-slim to minify this image docker-slim build rembg --http-probe=false

Specifications

• Version: 1.37.3
• Platform: MacOS - Darwin

Start with pkg/app/master/inspectors/container/container_inspector.go at FinishMonitoring and ShutdownContainer, then trace the build flow in pkg/app/master/commands/build/handler.go. Reproduce with the rembg Dockerfile, a 5GB image, and docker-slim build rembg --http-probe=false; done means the inspection completes without the missing creport.json 404 and the image is minified successfully.
