To get around this you can use the v2 APIs or use AQL queries against the release bundle repository:
curl -u <username> -X POST "<jfrogurl>/artifactory/api/search/aql" -H "Content-Type: text/plain" -d '
items.find({
"$or": [
{"repo": "<release bundle repository>"},
{"repo": "<release bundle repository>"}
]
}).include("name")'
