(beta4) Restore issue

Steps :

• Install fresh Chef 12.0.1-1
• Install beta4 (only beta2 is provided in the bundle)
• Create acme org, admin org-admin and jdoe user (with chef-server-ctl cli)
• bootstrap some nodes with few cookbooks (2 servers running a chef-server wrapper in my case)
• Do a backup and save it :-)
• Trash and install chef-server again with gem beta4
• Get back and restore previous backup

Restore :

# /opt/opscode/embedded/bin/knife ec restore ./backup
WARNING: No knife configuration file found
WARNING: chef_server_root not found in knife configuration; using chef_server_url
Restoring users ...
WARNING: Skipping pivotal user.  To overwrite pivotal, pass --overwrite-pivotal.
Restoring the org admin data
Restoring the rest of the org
Updated /clients/acme-validator.json
Created /clients/chef-01.json
Created /clients/chef-02.json
Created /clients/acme-validator.json
ERROR: internal server error
Response: internal service error

Result :

• org is restored
• users are restored
• groups/acl are restored
• clients and validator key are restored
• the rest is missing (cookbooks, nodes, ...)

Start by reproducing the failure with Chef 12.0.1-1, beta4, and the documented knife ec restore ./backup command. Inspect the restore stages after clients and the validator key are restored, then verify that cookbooks and nodes are restored without the internal server error.
