Check Existing Issues

I have searched for any existing and/or related issues.
I have searched for any existing and/or related discussions.
I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

v0.8.12

Ollama Version (if applicable)

No response

Operating System

Ubuntu 24.04

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

no exeception - just deleting the knowledge base

Actual Behavior

When deleting an older knowlegde base - created with 0.6.x - you get an:

| pydantic_core._pydantic_core.ValidationError: 1 validation error for ModelForm | access_grants.0 | Input should be a valid dictionary [type=dict_type, input_value=AccessGrantModel(id='9310..., created_at=1773243475), input_type=AccessGrantModel]

Steps to Reproduce

Unclear how reproduce. Seems that knowledge bases created with v0.6.28 seem to be affected when being deleted with v0.8.x.

+------------------------------------`

Additional Information

Fix seems to be simple in backend/open_webui/routers/knowledge.py - line 904++

By replacing:

                # Create a ModelForm for the update
                model_form = ModelForm(
                    id=model.id,
                    name=model.name,
                    base_model_id=model.base_model_id,
                    meta=model.meta,
                    params=model.params,
                    access_grants=model.access_grants,
                    is_active=model.is_active,
                )

with

                model_payload = model.model_dump()
                model_payload['meta'] = model.meta
                model_form = ModelForm(**model_payload)
                Models.update_model_by_id(model.id, model_form, db=db)

Worked for me.

+------------------------------------` ### Additional Information Fix seems to be simple in backend/open_webui/routers/knowledge.py - line 904++ By replacing: ``` # Create a ModelForm for the update model_form = ModelForm( id=model.id, name=model.name, base_model_id=model.base_model_id, meta=model.meta, params=model.params, access_grants=model.access_grants, is_active=model.is_active, ) ``` with ``` model_payload = model.model_dump() model_payload['meta'] = model.meta model_form = ModelForm(**model_payload) Models.update_model_by_id(model.id, model_form, db=db) ``` Worked for me.
