autoTenantCreation not working - object insert returns tenant not found

[owieboy]

How to reproduce this bug?

Create/update a collection and set the following properties

{
...
   "multiTenancyConfig": {
        "enabled": true,
        "autoTenantCreation": true
      },
...
}

Verify property was successfully set:
GET http://localhost:8080/v1/schema/TestSchema

...
    "multiTenancyConfig": {
        "autoTenantCreation": true,
        "enabled": true
    },
...

Using REST API, insert this test object and set tenant with a value for tenant name that has not been (manually) created yet:
POST http://localhost:8080/v1/objects

{
  "class": "TestSchema",
  "properties": {
    "account_id": "1"
  },
  "vector": [
    1
  ],
  "tenant": "TEST1234"
}

What is the expected behavior?

• Tenant TEST1234 to be created
• Test object inserted to the tenant

What is the actual behavior?

Result:

{
    "error": [
        {
            "message": "put object: import into index nsobject: determine shard: tenant not found: \"TEST1234\""
        }
    ]
}

Hey @owieboy thanks for your report!

Auto tenant creation is actually only available during batch importing.

This wasn't super clear in the docs, and we have since made a change to clarify this.

Additionally, I've improved the error message that occurs in this case (multi-tenancy and autoTenantCreation are enabled, and a single object insert is attempted with a non-existent tenant) here with #4948. This will be included in the next patch release, 1.25.1.

Apologies for the miscommunication on our part!

Thank you for the the clarifications. I can confirm that the tenant auto creation and data insertion indeed work when using batch operation.

POST http://localhost:{{WEAVIATE_PORT}}/v1/batch/objects

{
  "fields": [
    "ALL"
  ],
  "objects": [
    {
    "class": "TestSchema",
    "properties": {
        "account_id": "1"
    },
    "vector": [
        1
    ],
    "tenant": "TSTDRV1234"
    }
  ]
}
