Bedrock LLM Error With Browser Extract

by ADMIN 39 views

Introduction

Large Language Models (LLMs) have revolutionized the way we interact with technology, enabling us to perform complex tasks with ease. However, like any other software, LLMs are not immune to errors. In this article, we will delve into the world of Bedrock LLM error with browser extract, exploring the root cause of the issue and providing a step-by-step guide to resolve it.

Bug Description

OpenManus, a popular tool for extracting content from web pages, has stopped working with Bedrock due to an unexpected error. The error message reads:

"Unexpected error in ask_tool: An error occurred (ValidationException) when calling the Converse operation: A conversation must start with a user message. Try again with a conversation that starts with a user message."

This error occurs because the message log uses only a system prompt, without a user prompt. To resolve this issue, we need to modify the system prompt to include a user prompt.

Bug Solved Method

The solution to this bug lies in modifying the browser_use_tool.py file in the app/tool directory. Specifically, we need to change the messages variable to include a user prompt.

diff --git a/app/tool/browser_use_tool.py b/app/tool/browser_use_tool.py

+                                {"role": "user", "content": f"Page content: {content[:max_content_length]}"}]

                     # Define extraction function schema
                     extraction_function = {

As you can see, the messages variable now includes a user prompt with the content of the page. This change resolves the error and allows OpenManus to work with Bedrock again.
