Check Existing Issues

• I have searched for any existing and/or related issues.
• I have searched for any existing and/or related discussions.
• I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

v0.6.33

Ollama Version (if applicable)

No response

Operating System

Debian 12

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

When performing web searches using Google PSE (Programmable Search Engine), the system should:

1. Successfully retrieve and process web search results
2. Store the results in the PostgreSQL vector database without errors
3. Maintain stable memory usage across multiple search requests
4. Allow users to reference the search results in their conversations

Actual Behavior

When using Google PSE web search with PostgreSQL/pgvector backend:

1. Web search requests work successfully - users receive search results in their chat and can interact with them normally
2. However, backend logs show database insertion failures due to NUL characters in scraped content
3. The search results fail to be stored as vector embeddings in the PostgreSQL database
4. Each web search request causes a persistent 300MB memory increase in server RAM usage
5. After multiple web search requests, our server RAM fills up completely, crashes the server, and requires a manual reboot to restore functionality

Steps to Reproduce

Prerequisites:

• Open WebUI v0.6.33 running in Docker
• PostgreSQL database with pgvector extension enabled
• Google PSE API configured with valid API key and Search Engine ID

Reproduction Steps:

1. Start Open WebUI with the above configuration
2. Navigate to a chat interface
3. Enable web search in the chat settings
4. Send a message that triggers a web search (e.g., "Search for recent news about AI")
5. Observe the server logs for the database error
6. Monitor server memory usage - note ~300MB increase
7. Repeat steps 4-6 multiple times
8. Observe cumulative memory increase and eventual server instability
