File Search documents.list returns corpora/* validation error (regression)

[philo92]

Summary:
Calling documents.list on a File Search Store returns an INVALID_ARGUMENT error
requesting corpora//documents/ format, even though the endpoint is
fileSearchStores/*/documents.

This worked previously and now fails.

Reproduction:
curl -X GET
"https://generativelanguage.googleapis.com/v1beta/fileSearchStores/STORE_ID/documents?key=API_KEY"

Response:
{
"error": {
"code": 400,
"message": "Document name must be of the format corpora//documents/",
"status": "INVALID_ARGUMENT"
}
}

Notes:

• Same error with curl and application client
• fileSearchStores.get works
• documents.list fails consistently
• Appears to be routed/validated as corpora documents API

Environment:

• API: Gemini / Generative Language API
• Version: v1beta
