Incorrect vectorizer set in collection schema (text2vec-google vs text2vec-palm)

General

Hi everyone,

I’m running into an issue where my collection is being created with text2vec-palm as the vectorizer, even though I’ve set everything to use text2vec-google (Gemini embeddings).

vectorizer_config = wvc.config.Configure.Vectorizer.text2vec_google(
project_id=“myid”,
)

Docker Compose setup

volumes:
  - weaviate_gemini:/var/lib/weaviate
  - ./credentials/google_credentials.json:/etc/weaviate/google_credentials.json:ro
restart: on-failure:0
environment:
  QUERY_DEFAULTS_LIMIT: 5000
  AUTHENTICATION_ANONYMOUS_ACCESS_ENABLED: "true"
  PERSISTENCE_DATA_PATH: "/var/lib/weaviate"
  ENABLE_API_BASED_MODULES: true
  DEFAULT_VECTORIZER_MODULE: text2vec-google
  ENABLE_MODULES: text2vec-google
  CLUSTER_HOSTNAME: "node1"
  MODULES_CLIENT_TIMEOUT: "1h"
  USE_GOOGLE_AUTH: "true"
  GOOGLE_APPLICATION_CREDENTIALS: "/etc/weaviate/google_credentials.json"

Actual schema being created

{
  "class": "Collection_ddd",
  "invertedIndexConfig": {
    "bm25": { "b": 0.75, "k1": 1.2 },
    "cleanupIntervalSeconds": 60,
    "stopwords": { "preset": "en" }
  },
  "moduleConfig": {
    "text2vec-palm": {
      "modelId": "gemini-embedding-001",
      "projectId": "***removed***",
      "vectorizeClassName": true
    }
  },
  "properties": [
    {
      "name": "fileId",
      "dataType": ["text"],
      "moduleConfig": {
        "text2vec-palm": { "skip": true, "vectorizePropertyName": true }
      }
    },
    {
      "name": "fileContent",
      "dataType": ["text"],
      "moduleConfig": {
        "text2vec-palm": { "skip": false, "vectorizePropertyName": true }
      }
    }
  ],
  "vectorIndexConfig": { "distance": "cosine" },
  "vectorIndexType": "hnsw",
  "vectorizer": "text2vec-palm"
}

Even though I’m using text2vec-google in both my Docker config and collection creation code, the schema always ends up with text2vec-palm as the vectorizer.

When I try to query, I get this error:

no vectorizer module “text2vec-palm” is configured

Versions

  • Weaviate server: 1.27.4

  • Weaviate Python client: 4.10.1

Hey @Muhammad_Ashir ,

It’s just module name change text2vec-google was called text2vec-palm in Weaviate versions prior to v1.27

Also It would be great if you upgrade your Weaviate to latest as you are way outdated - we are almost releasing 1.33
