Dify version

0.6.16

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

I was trying to config my knowledge base, but it told me there was a client-side exception. knowledgebase-exception I guess it was caused by some version mistakes of certain python packages, but I'm not sure how to solve it. The error message is below.

✔️ Expected Behavior

No response

❌ Actual Behavior

To resolve the client-side exception and deprecation warnings you're encountering in Dify v0.6.16, follow these steps:

Update Python Packages: Ensure that the Python packages are updated to their latest compatible versions. You can do this by updating the requirements.txt file and using Poetry to manage dependencies.
```
poetry shell
poetry add $(cat requirements.txt)
poetry add $(cat requirements-dev.txt) --group dev
```
Handle Deprecation Warnings: The deprecation warnings indicate that certain methods are deprecated and should be replaced. Specifically:
- Replace copy with model_copy.
- Replace validate with model_validate.
Update your code to use these new methods as per the Pydantic V2 Migration Guide.

Configure SSL/TLS: Ensure that your self-hosted instance is using secure connections. Update your environment variables to use https URLs and configure SSL/TLS in your Docker setup.

Example environment variables:

CONSOLE_API_URL=https://api.console.dify.ai
CONSOLE_WEB_URL=https://console.dify.ai
SERVICE_API_URL=https://api.dify.ai
APP_API_URL=https://app.dify.ai
APP_WEB_URL=https://api.app.dify.ai

Example Nginx configuration for SSL termination:

server {
   listen 443 ssl;
   server_name your_domain.com;

   ssl_certificate /path/to/your/certificate.crt;
   ssl_certificate_key /path/to/your/private.key;

   location / {
       proxy_pass http://your_application_container:5001;
       proxy_set_header Host $host;
       proxy_set_header X-Real-IP $remote_addr;
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       proxy_set_header X-Forwarded-Proto $scheme;
   }
}

Check Vector Search Settings: Ensure that the vector search settings are correctly configured for English queries. Adjust the TopK, Score threshold, and Rerank model settings as needed.
```
TopK: 3
Score threshold: 0.5
Rerank model: <API_KEY>
```

By following these steps, you should be able to resolve the client-side exception and deprecation warnings, ensuring a secure and functional setup for your knowledge base ^[1]^[2]^[3]^[4].

Hello can you paste the errors in web console? It seems to be a frontend issue.

To address the frontend issues you're encountering, follow these steps:

Deprecation Warnings for -ms-high-contrast-adjust: These warnings are related to CSS properties that are no longer supported. Update your CSS to remove or replace deprecated properties.
403 Error for Failed Resource Load: This error indicates a permission issue. Ensure that the resource URL is correct and that the server has the necessary permissions to access it. Check your server configuration and authentication settings.
TypeError: Cannot Read Properties of Undefined (Reading 'extension'): This error suggests that a variable is being accessed before it is defined. Use optional chaining to prevent this error:
```
const extension = someObject?.extension;
```
TypeError: Cannot Read Properties of Null (Reading 'postMessage'): Similar to the previous error, this indicates that a null value is being accessed. Ensure that the object is not null before accessing its properties:
```
if (someObject !== null) {
   someObject.postMessage(...);
}
```
General Debugging Steps:
- Use Browser Developer Tools: Set breakpoints and inspect variables to identify where the errors are occurring.
- Check for Undefined or Null Values: Add checks in your code to handle undefined or null values gracefully.
- Review Code for Common Issues: Ensure that your code safely accesses properties and handles potential errors.

By following these steps, you should be able to resolve the client-side exceptions and improve the stability of your frontend application ^[1].
