Description:

The new API endpoint /api/v2/saved-queries/export in BHCE v8.2.0 does not export multiple saved queries at once as advertised in the endpoint's description.

Are you intending to fix this bug?

no

Component(s) Affected:

• API

Steps to Reproduce:

1. Go to the API Explorer
2. Try out the /api/v2/saved-queries/export "Export one or more saved queries" endpoint
3. Receive a Bad Request error indicating that only one query can be exported

Expected Behavior:

The description of the endpoint says

The response ZIP file will contain JSON files using their query name as the file name.

This indicates the export of multiple queries at once is supported.

Actual Behavior:

Instead, the following HTTP error is returned:

{
  "http_status": 400,
  "timestamp": "2025-09-29T10:49:10.747042724Z",
  "request_id": "69693116-b8e4-4260-890d-780bd7be0fea",
  "errors": [
    {
      "context": "",
      "message": "id is malformed."
    }
  ]
}

This sounds like a specific query ID is missing, and calling /api/v2/saved-queries/<queryID>/export as the UI is doing works indeed.
However, this is contrary to the endpoint's description and is not documented this way.
