deleteMany is not working as expected when multi tenancy is enabled JavaScript client ( v3.8.0)

Context:
I’m using the weaviate-client (v3.8.0) for JavaScriptand trying to perform a deleteMany operation in a multi-tenant collection using the documented tenant option.

Code That Fails:

const response = await collection.data.deleteMany(
  collection.filter.byProperty('docId').containsAny(docIds),
  {
    tenant: tenantName
  }
);

Error:
The client throws an error that no tenant was specified, even though it was provided in the argument.

Investigation:
Looking into the client source code at:
weaviate-client/dist/node/cjs/collections/data/index.js

The relevant code is:

deleteMany: (where, opts) =>
  connection
    .batch(name, consistencyLevel, tenant) // tenant is undefined here
    .then((batch) =>
      batch.withDelete({
        filters: Serialize.filtersGRPC(where),
        dryRun: opts?.dryRun,
        verbose: opts?.verbose,
      })
    )

The issue is that tenant is being passed to connection.batch(...), but it’s never assigned from opts. So even if I provide opts.tenant, it doesn’t get used.

Expected Fix:
The code should extract the tenant from the options like this:

const tenant = opts?.tenant;

or

.batch(name, consistencyLevel, opts?.tenant)

Please confirm if this is a known issue, or if I’m using the API incorrectly. Happy to provide more details or help test a fix.

Hey @nikhil1728, thanks for flagging this. Could you try and use the client as documented here?

If the issue persists could you open an issue on the client repo?

Hi @malgamves thanks! It works as follows:

const collection = client.collections.get(indexName);
const tenant = collection.withTenant(tenantName);
const response = await tenant.data.deleteMany(
  tenant.filter.byProperty('docId').containsAny(docIds)
);
