Description

Hi,

I'm using this documentation to configure crane and pulp-docker https://docs.pulpproject.org/en/2.6/pulp-docker.pdf

I have do this :

pulp-admin docker repo create --repo-id=busybox
pulp-admin docker repo uploads upload --repo-id=busybox -f /home/poil/busybox.tar
pulp-admin docker repo update --repo-id=busybox --repo-registry-id=repos.local/busybox
pulp-admin docker repo publish run --repo-id=busybox

Now when I go on https://repos.local:8443/crane/repositories/v2 I have my repo listed
But when I go with curl to have the json output I have a 500 Internal Server Error with this traceback :

Also I have the same traceback when doing a pull

# docker pull repos.local:8443/busybox 
Using default tag: latest

/etc/crane.conf :
