Kaniko cache warmer fails to download said image

[rjdp]

Actual behavior when running: docker run -v $(pwd):/workspace gcr.io/kaniko-project/warmer:latest --cache-dir=/workspace/cache --image=python:3.5.9-buster

I get error: Failed warming cache: Failed to write python:3.5.9-buster to tar buffer: stream error: stream ID 21; PROTOCOL_ERROR

Expected behavior Should successfully download layers image and populate warmer cache

To Reproduce Steps to reproduce the behavior:

1. docker run -v $(pwd):/workspace gcr.io/kaniko-project/warmer:latest --cache-dir=/workspace/cache --image=python:3.5.9-buster
