Expected Behavior

Summary: When uploading files to a knowledge base via the API, the operation completes successfully (200 OK), but the knowledge becomes inaccessible in the user interface from version v0.6.6.

In Open WebUI v0.6.5, the same Python script and API workflow worked perfectly - downloaded files were accessible and the knowledge base could be opened and queried via the interface.

Since v0.6.6 and higher (tested in v0.6.10), the knowledge base becomes broken/inaccessible in the user interface after a file has been uploaded via the API.

Sample Python Script Used:

import requests

API_URL = "http://localhost:8080"
API_KEY = "sk-rezrzez"
KNOWLEDGE_ID = "rezrzez-rezrzez-rezrzez-rezrzez-rezrzez"
FILE_PATH = "/home/webui/scripts/glpi/files_glpi/ticket.txt"

headers_upload = {
    "Authorization": f"Bearer {API_KEY}",
    "Accept": "application/json"
}

headers_json = {
    "Authorization": f"Bearer {API_KEY}",
    "Content-Type": "application/json"
}

upload_url = f"{API_URL}/api/v1/files/"

with open(FILE_PATH, "rb") as f:
    files = {"file": f}
    upload_response = requests.post(upload_url, headers=headers_upload, files=files)

if upload_response.status_code == 200:
    file_id = upload_response.json().get("id")
    print(f"✅ Fichier téléversé avec succès. ID du fichier : {file_id}")
else:
    print(f"❌ Erreur lors du téléversement : {upload_response.status_code} - {upload_response.text}")
    exit(1)

associate_url = f"{API_URL}/api/v1/knowledge/{KNOWLEDGE_ID}/file/add"
data = {"file_id": file_id}

associate_response = requests.post(associate_url, headers=headers_json, json=data)

if associate_response.status_code == 200:
    print("✅ Fichier associé avec succès à la base de connaissances.")
else:
    print(f"❌ Erreur lors de l'association : {associate_response.status_code} - {associate_response.text}")

Actual Behavior

Hello,

When uploading a file to a knowledge base using the API, the system returns 200 OK and reports the knowledge base as updated. However, trying to access it via the UI causes a frontend crash.

Steps to reproduce:

Upload a file via /api/v1/files/ (even a minimal .txt file).

Associate it with the knowledge base using /api/v1/knowledge/{id}/file/add.

Go to the knowledge base in the UI.

Result:
The knowledge becomes inaccessible in the WebUI.
In the browser console, I get this error:

FileItemModal.svelte:28 Uncaught (in promise) TypeError: Cannot read properties of null (reading 'startsWith')
at r.$$.update (FileItemModal.svelte:28:28)
at Pt (Component.js:144:5)
at new nt (FileItemModal.svelte:33:59)

at gt (ArrowUpCircle.svelte:3:27)
at fl (Files.svelte:14:8)
at Pt (Component.js:148:34)

Uploading the same file via the UI interface (without API) works fine.

Tested on Open WebUI version 0.6.10.
