[BUG] Unsupported data type when using PDFSearchTool

[sorin-costea]

Description

I get this error:

I encountered an error while trying to use the tool. This was the error: Unsupported data type.
 Tool Search a PDF's content accepts these inputs: Search a PDF's content(query: 'string') - A tool that can be used to semantic search a query the my.pdf PDF's content. query: 'Mandatory query you want to use to search the PDF's content'
# Agent: Researcher...
## Thought: In order to ...
## Using tool: Search a PDF's content
## Tool Input:
"{\"query\": \"key skills and qualifications\"}"

Steps to Reproduce

The code I use is (fluff removed for clarity):

from crewai_tools import PDFSearchTool
my_file_tool = PDFSearchTool(config=azure_config, pdf='my.pdf')
my_researcher = Agent(
    role="Researcher...",
    goal="Make sure to...",
    backstory=("As a..."),
    tools=[job_file_tool],
    ...
)
my_task = Task(
    description=("Analyze..."),
    agent=my_researcher,
    tools=[my_file_tool],
    ...
)
crew_test = Crew(
    agents=[my_researcher],
    tasks=[my_task],
    process=Process.sequential,
    full_output=True,
    verbose=True
)

Expected behavior

As I cannot influence the format of what the agent sends to the tools, I'd expect the agent would send properly query=string. Could it be the config=... is messing up things?

Additional context

Same behaviour when I use the DOCXSearchTool, so there's either something I completely misunderstand, or worse.
