Original GitHub issue: https://github.com/open-webui/open-webui/issues/14432

Check Existing Issues

  • I have searched the existing issues and discussions.
  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

0.6.11

Ollama Version (if applicable)

No response

Operating System

Debian 6.12.17-1

Browser (if applicable)

No response

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have provided every relevant configuration, setting, and environment variable used in my setup.
  • I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
  • I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
  • Start with the initial platform/version/OS and dependencies used,
  • Specify exact install/launch/configure commands,
  • List URLs visited, user input (incl. example values/emails/passwords if needed),
  • Describe all options and toggles enabled or changed,
  • Include any files or environmental changes,
  • Identify the expected and actual result at each stage,
  • Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

curl -X 'POST' \
  'http://localhost:3000/api/v1/retrieval/query/collection' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{
  "collection_names": [
    "xxx"
  ],
  "query": "my query",
  "k": 0,
  "k_reranker": 0,
  "r": 0,
  "hybrid": true
}'

should return 200 as aspected

Actual Behavior

Same call now return 400

{
  "detail": "[ERROR: 'QueryCollectionsForm' object has no attribute 'hybrid_bm25_weight']"
}

Steps to Reproduce

1.Pulled new docker version ghcr.io/open-webui/open-webui:main
2.Up the service
3.With api create a new user with a group, create a model only for that user with private visibility, create a knowledge with some files and add this to the model
4.Make the api request to /api/v1/retrieval/query/collection
5.Get the response with 200 status code

Additional Information

Maybe missing field into the BaseModel from backend/open_webui/routers/retrieval.py#L1831

    query: str

the interface of ollama has changed so open-webui can't get embeddings.

there are no response when using blow commands:

# no reponse
curl -X POST http://host.docker.internal:11434/api/embed -d '{"model": "bge-m3", "input": "Open WebUI is great!"}' 

curl -X POST http://host.docker.internal:11434/api/embeddings -d '{"model": "bge-m3", "input": "Open WebUI is great!"}' 
# response: {"embedding":[]}

using below command got correct result(note 'input' has changed to 'prompt'):

curl -X POST http://host.docker.internal:11434/api/embeddings -d '{"model": "bge-m3", "prompt": "Open WebUI is great!"}'
# response: {"embedding":[-1.3994859457015991,-0.3196967542171478....]

what ollama version do you use?
update it!

/api/embeddings...Note: this endpoint has been superseded by /api/embed

0.6.12 did not fix the issue. Still getting 400's especially when pasting anything.
