ids must be provided

Error message

ids must be provided

What it means

Thrown by the generic PUT .../bulk endpoint on ProviderControllerBase (the base for indexers, download clients, notifications, etc.) when the bulk provider resource's Ids collection is empty. A bulk update needs target provider ids to apply changes to, so an empty set is a bad request.

Solutions

1. Include at least one provider id in the Ids array of the bulk request body.
2. Disable bulk-edit controls in the UI until at least one provider row is selected.

Example fix

// before
PUT /api/v3/indexer/bulk
{ "ids": [], "tags": [2], "applyTags": "add" }
// after
PUT /api/v3/indexer/bulk
{ "ids": [1, 4], "tags": [2], "applyTags": "add" }

if (providerResource.Ids is null || !providerResource.Ids.Any()) {
    return BadRequest("Select at least one provider id for the bulk update.");
}

static bool HasIds<T>(T bulk) where T : IBulkProviderResource
    => bulk?.Ids?.Any() == true;

When it happens

Trigger: A PUT to /api/v3/{provider}/bulk (e.g. indexer, downloadClient, notification) with a body whose Ids list is empty.

Common situations: A bulk tag-edit action in the UI invoked with no providers selected; a script applying tag changes to an empty filtered list; a client sending an empty ids array.
