[Serper Agent] Weird issue with using Serper Agent

[aditya-opsverse]

Hello team,

I'm encountering an issue when using the Serper tool. Here's the error message I get:

Error executing tool. coworker mentioned not found, it must be one of the following options:
- postgresql specialist
- web search and data retrieval specialist

The error only occurs when I'm using the Serper tool or "web search and data retrieval specialist" role. This issue is not seen with other roles or Agents.

Configurations:

serper_agent_params = {
    "role": "Web Search and Data Retrieval Specialist",
    "goal": """
        Your goal is to analyze user queries and perform web searches using the search_internet tool.
    """,
    "backstory": "Your strength lies in interpreting user queries and understanding intent while providing the best-matching search results that reflect the latest trends and developments. You excel at gathering structured data from web pages, filtering out unnecessary details, and presenting useful, actionable insights.",
    "allow_delegation": True,
    "verbose": True,
    "llm": openai_llm,
}

class search_internet(BaseTool):
    name: str = "Search The Internet"
    description: str = (
        """
        Given a query, search the internet for information and return relevant results.

        Args
        - query (str): The query to search.

        Returns
        - JSON str: Formatted JSON string with title, link, and snippet.
        """
    )
    ...

However, when I replace

"role": "Web Search and Data Retrieval Specialist",

with

"role": "web search and data retrieval specialist",

Everything works as expected and no error logs are seen.

Please let me know why this is happening and what change to be made to resolve this issue without changing the role strings to lowercase.

Thank you.
