What happened?

While using the local vision model for browser use, it throws an error - 'url' field must be a base64 encoded image.

Steps to reproduce

1. Launch the local vision model.
2. In HAI Code Generator, set up the local model in API Configuration by choosing the correct provider.
3. Ensure that Browser Settings are enabled.
4. Start a new chat and input a prompt intended for browser usage (e.g., “Open the browser and search for an available electronics product”).
5. Once the browser initially opens, an error appears on the client side as a generic message, while the actual error is recorded on the server side.
