Description of problem:
I tried to get the logs of failed installation and got this from the link:
{"code":"500","href":"","id":500,"kind":"Error","reason":"No log files were found"}

Version-Release number of selected component (if applicable):


How reproducible:

1/1
Steps to Reproduce:
1. Create the following:
BMH
pull-secret
manifest that will fail the cluster installation (see content below, though it doesn't really matter how you fail the installation)
infra-env
agent-cluster-install (with the manifestsConfigMapRef)
cluster-deployment

2. describe the Agentclusterinstall once the installation fails
3. curl the logs link to get the logs

Actual results:

{"code":"500","href":"","id":500,"kind":"Error","reason":"No log files were found"}

Expected results:
Get the cluster logs

Additional info:

I can log into the host, the assisted-installer-controller did upload the logs:
