All PSIRT openVuln API: "NO_DATA_FOUND"

[llxxzz12]

Describe the bug
I am using a python script to retrieve the data of certain bug IDs. The process is working for some and returning errors for others – Could you please be as kind as to help to me to address this issue or any further requirement? It doesn't seem to have a pattern as some IDs are fetched while others not. It seems to be linked with certain defect IDs.

To Reproduce
Steps to reproduce the behavior:
Get BugID via Cisco Bug Identifier:

curl -X GET -H "Accept: application/json" -H "Authorization: Bearer " 'https://apix.cisco.com/security/advisories/v2/bugid/CSCwd28131'

Expected behavior
{
"advisories": [
{
"advisoryId": "cisco-sa-expressway-csrf-KnnZDMj3",
"advisoryTitle": "Cisco Expressway Series Cross-Site Request Forgery Vulnerabilities",
"bugIDs": [
"CSCwa25074",
"CSCwa25099",
