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
The Models are loaded by the SentenceTransformer and embedding vectors are generated
Actual Behavior
the retrieval process crashes
Steps to Reproduce
configure jinaai/jina-embeddings-v4 as embedding model
set 'SENTENCE_TRANSFORMERS_MODEL_KWARGS={"default_task": "retrieval"}'
upload a document to a knowledge
Logs & Screenshots
400: 'NoneType' object has no attribute 'encode'
