Amadeus searchflight not working

[SiruX21]

Checked other resources

• I added a very descriptive title to this issue.
• I searched the LangChain documentation with the integrated search.
• I used the GitHub search to find a similar question and didn't find it.
• I am sure that this is a bug in LangChain rather than my code.

Example Code

from langchain_google_genai import ChatGoogleGenerativeAI
from langchain_community.agent_toolkits.amadeus.toolkit import AmadeusToolkit
from langchain import hub
from langchain.agents import AgentExecutor, create_react_agent
llm = ChatGoogleGenerativeAI(model="gemini-pro")
toolkit = AmadeusToolkit(llm=llm)
tools = toolkit.get_tools()
prompt = hub.pull("sirux21/react")
agent = create_react_agent(llm, tools, prompt)
val = {
     "input": "Find flights from NYC to LAX tomorrow",
}
agent_executor = AgentExecutor(
    agent=agent,
    tools=tools,
    verbose=True,
    agent=AgentType.STRUCTURED_CHAT_ZERO_SHOT_REACT_DESCRIPTION,
)

agent_executor.invoke(val)

Hey @SiruX21, great to see you back with us! How's everything going on your end?

Thank you for providing the detailed error log. It seems like the issue is related to the input parameters for the FlightSearchSchema in the AmadeusToolkit. The error message indicates that the destinationLocationCode, departureDateTimeEarliest, and departureDateTimeLatest fields are missing.

Based on the context provided, the FlightSearchSchema expects the following input parameters:

1. originLocationCode: A string representing the three-letter International Air Transport Association (IATA) Location Identifier for the search's origin airport.

2. destinationLocationCode: A string representing the three-letter International Air Transport Association (IATA) Location Identifier for the search's destination airport.

3. departureDateTimeEarliest: A string representing the earliest departure datetime from the origin airport for the flight search in the following format: "YYYY-MM-DDTHH:MM", where "T" separates the date and time components. For example: "2023-06-09T10:30:00" represents June 9th, 2023, at 10:30 AM.

4. departureDateTimeLatest: A string representing the latest departure datetime from the origin airport for the flight search in the same format as departureDateTimeEarliest.

5. page_number: An integer representing the specific page number of flight results to retrieve. It defaults to 1 if not provided.

From the error log, it seems like the destinationLocationCode, departureDateTimeEarliest, and departureDateTimeLatest fields are not being passed correctly to the FlightSearchSchema. Please ensure that these fields are included in the Action Input for the single_flight_search action.

Here is an example of how the Action Input should look like:

{
    "originLocationCode": "JFK",
    "destinationLocationCode": "LAX",
    "departureDateTimeEarliest": "2023-06-08T00:00:00",
    "departureDateTimeLatest": "2023-06-08T23:59:59"
}

Please try updating your Action Input and let me know if the issue persists.

@dosu-bot If you look, that is exactly what is passed through,

Action Input: {
"originLocationCode": "JFK",
"destinationLocationCode": "LAX",
"departureDateTimeEarliest": "2023-06-08T00:00:00",
"departureDateTimeLatest": "2023-06-08T23:59:59"
}

by the agent AI, and the issue still persists.

From the error message you provided, it seems like the FlightSearchSchema is not receiving the required fields (destinationLocationCode, departureDateTimeEarliest, departureDateTimeLatest). However, from the action input you provided, it seems like these fields are indeed being passed correctly.

This discrepancy could be due to a few reasons:

1. Data Flow Issue: There might be an issue with how the data is being passed from the agent to the FlightSearchSchema. To debug this, you could print the data being passed right before it's sent to the FlightSearchSchema and check if it matches the action input you provided.

2. Schema Validation Issue: There might be an issue with the FlightSearchSchema itself. You could try creating a FlightSearchSchema object directly with the action input you provided and see if it still throws a validation error.

Here's how you can do these:

# Debugging data flow
print("Data being passed to FlightSearchSchema:", val)
agent_executor.invoke(val)

# Debugging schema validation
from langchain_community.agent_toolkits.amadeus.schemas import FlightSearchSchema

try:
    flight_search = FlightSearchSchema(**{
        "originLocationCode": "JFK",
        "destinationLocationCode": "LAX",
        "departureDateTimeEarliest": "2023-06-08T00:00:00",
        "departureDateTimeLatest": "2023-06-08T23:59:59"
    })
    print("FlightSearchSchema created successfully:", flight_search)
except Exception as e:
    print("Error while creating FlightSearchSchema:", e)

If the data being passed is correct and the FlightSearchSchema is able to be created directly without any errors, then the issue might be somewhere else in the code. In that case, please provide more information about the steps leading up to the error and any other relevant code snippets.

If the data being passed is not correct, then there might be an issue with how the agent is generating the action input. In that case, you might need to debug the agent's code.

If the FlightSearchSchema is not able to be created directly, then there might be an issue with the FlightSearchSchema itself or the data being passed to it. In that case, please double-check the data and the FlightSearchSchema's requirements.

I hope this helps! Let me know if you have any other questions or if there's anything else I can do to assist you.

@SiruX21 did you solve it? I meet the same problem. Does prompt optimize work?

Hi,@SiruX21. This problem has be solved in the latest doc. Amadeus Tool
