AWS Lambda and Gateway API Integration Returns 500 Status Code

Question

First of all, I'm new to overall AWS. I am trying to solve a problem using AWS lambda and API gateway.

• I created a python lambda function function. It takes some data and returns stringbased on some conditions. Something like below:

def lambda_function(event, context):
    if event['some_property']:
        return "SUCCESS: Operation performed successfully."
    else
        return "ERROR: Operation failed."

2. In triggers, I configured the gateway API.

3. In the API gateway service for the created resource, the integration request is configured to go to the lambda function. I checked the lambda function and it returns the values ​​correctly.

4. But if I twist the API by creating a mail request, it returns a server error. This is a message.

{"message": "internal server error"}

5. . json application/json , .

, Integration Response -. 200 , .
