storage3 vectors list_indexes() drops next_token and max_results

[hsusul]

Bug report

VectorBucketScope.list_indexes() sends its pagination arguments under snake_case keys, but the Storage /vector/ListIndexes endpoint only understands camelCase. next_token and max_results are therefore silently ignored by the server.

https://github.com/supabase/supabase-py/blob/main/src/storage/src/storage3/_async/vectors.py#L76-L78

body = self.with_metadata(
    next_token=next_token, max_results=max_results, prefix=prefix
)

Every other vector request in the same file uses the wire names (maxResults, nextToken in list_buckets() and VectorIndexScope.list()), and the response model the SDK hands back is itself camelCase (ListVectorIndexesResponse.nextToken). The server's schema (list-indexes.ts) accepts vectorBucketName, maxResults, nextToken, prefix and does not reject unknown properties, so there is no error — the values just vanish. The sync client has the same code.

Impact

• max_results is ignored; the server always uses its default page size (500).
• next_token is ignored, so every "next page" request returns the first page again. The usual pagination loop never terminates for a bucket with more than one page of indexes:

page = await storage.vectors().from_("embeddings").list_indexes()
while page.nextToken:
    page = await storage.vectors().from_("embeddings").list_indexes(
        next_token=page.nextToken  # dropped on the wire -> same page forever
    )

Reproduction

import asyncio, json
from httpx import AsyncClient, MockTransport, Response
from storage3 import AsyncStorageClient

def handler(request):
    print(json.loads(request.content))
    return Response(200, json={"indexes": []})

async def main():
    storage = AsyncStorageClient(
        "https://example.supabase.co/storage/v1/",
        {"apikey": "key"},
        http_client=AsyncClient(transport=MockTransport(handler)),
    )
    await storage.vectors().from_("my-bucket").list_indexes(
        next_token="cursor-1", max_results=10
    )

asyncio.run(main())

Expected behavior

{'vectorBucketName': 'my-bucket', 'nextToken': 'cursor-1', 'maxResults': 10}

Actual behavior

{'vectorBucketName': 'my-bucket', 'next_token': 'cursor-1', 'max_results': 10}
