Query for retracted=true does not work

curl --connect-timeout 300 'https://1-5-test-esgf-esg-fastapi.apps.onyx.ccs.ornl.gov/?limit=0&project=obs4MIPs&facets=data_node&retracted=true'

Same count as leaving off the retracted keyword. The expected behavior is to return only the dataset records that match.
