FileReadTool - issue with input file_path

HI guys,
i have been trying to use the FileReadTool to read a csv file. The tool has been provided to an agent for it to use to read the csv file.

extractor_agent = Agent(
role=‘xxx’,
goal=“Extract all the relevant text based on the user_input given in by the user from the
input_file “,
backstory=””“xxxxx.”“”,
tools=[Reader_tool],
verbose=True,
llm=llm
)

results = master_crew.kickoff(
inputs={
“user_input” : “xxxx”,
“input_file” : “sample.csv”
}
)

but i am getting an error like this

Using tool: Read a file’s content

Tool Input:

“{"file_path": "input_file"}”

Tool Output:

Error: File not found at path: input_file

pls help out if anyone knows how to proceed with this. i know that the tool can be initialized with file path by giving it as an arguement inside FileReadTool while declaring it but how to pass that argument from the inputs given in crew.kickoff
