Getting an error
I encountered an error while trying to use the tool. This was the error: extract_text_tool() missing 1 required positional argument: ‘file_path’.
Tool Extract Text Tool accepts these inputs: Tool Name: Extract Text Tool

Please revise your post formatting so that the code is enclosed in three consecutive single backticks. Which represents a code block.
Is your tool located in \src<crew-folder>\tools\custom_tool.py?

Change your function like:

    @tool(“Extract Text Tool”)
    def extract_text_tool(file_path: str) -> str:

You are using the decorator, if this approach doesnt work try creating you tool by subclassing BaseTool. Create Custom Tools - CrewAI

Hope this helps somehow. I am new to crewai myself and also struggle with creating my own custom tool. :wink:
