   ### Apache Airflow version
   
   main (development)
   
   ### If "Other Airflow 2 version" selected, which one?
   
   _No response_
   
   ### What happened?
   
   When invoking lambda functions using `LambdaInvokeFunctionOperator`, the 
task continues to run even after the actual lambda invocation is completed. It 
then throws a `ReadTimeoutError`.
   
   It is more common with Lambda functions that take more than 13 minutes to 
run. For Lambda functions that take more than 4 minutes, this is common when 
multiple tasks with `LambdaInvokeFunctionOperator` are triggered(I.e., Invoke 
the same lambda).
   
   I have followed the recommended settings as mentioned 
[here](https://airflow.apache.org/docs/apache-airflow-providers-amazon/stable/operators/lambda.html#invoke-an-aws-lambda-function):
   
   My AWS connection extra parameter has the following json
   ```
   {
   "config_kwargs": {
       "connect_timeout": 5,
       "read_timeout": 900,
       "tcp_keepalive": true,
       "retries": {
         "max_attempts": 0
       }
     }
   }
   ```
   
   I did set the max timeout to 15 minutes for the lambda function on AWS.
   
   For the mentioned recommendations on the docs:
   
   1. [NAT Gateway Troubleshooting: Internet connection drops after 350 
seconds](https://docs.aws.amazon.com/vpc/latest/userguide/nat-gateway-troubleshooting.html#nat-gateway-troubleshooting-timeout)
   
   >  I have noticed this issue even with lambda functions that take 4 minutes 
to run. However, ReadTimeouts occur relatively rarely and mostly happen when 
running multiple invocations in quick succession.
   
   
   2. [Using TCP keepalive under 
Linux](https://tldp.org/HOWTO/TCP-Keepalive-HOWTO/usingkeepalive.html)
   
   > I have updated `sysctl.conf` as below:
   ```
   echo "net.ipv4.tcp_keepalive_time = 320" >> /etc/sysctl.conf 
   echo "net.ipv4.tcp_keepalive_intvl = 60" >> /etc/sysctl.conf 
   echo "net.ipv4.tcp_keepalive_probes = 20" >> /etc/sysctl.conf
   ```
   
   ### What you think should happen instead?
   
   Tasks Should not run beyond the actual completion of the lambda invocations. 
   
   ### How to reproduce
   
   Use the following   DAG:
   
   ```
   from datetime import datetime
   from airflow import DAG
   from airflow.providers.amazon.aws.operators.lambda_function import 
LambdaInvokeFunctionOperator
   
   default_args = {
       'owner': 'airflow',
       'start_date': datetime(2024, 1, 1),
   }
   
   with DAG('invoke_lambda_dag', default_args=default_args, 
schedule_interval=None, catchup=False) as dag:
       invoke_lambda_task = LambdaInvokeFunctionOperator(
           task_id='invoke_lambda',
           function_name='runForFifteenMinutes',
           payload='{"key1": "value1","key2": "value2","key3": "value3"}',
           aws_conn_id='aws'
       )
   ```
   
   Create an AWS connection with the following json in the extra(You might need 
to add AWS `aws_session_token` and `region_name` to the extra:
   
   ```
   {
   "config_kwargs": {
       "connect_timeout": 5,
       "read_timeout": 900,
       "tcp_keepalive": true,
       "retries": {
         "max_attempts": 0
       }
     }
   }
   
   ```
   
   On AWS, create a lambda function, and update timeout to 15 minutes(That is 
the max possible value)
   
   You can add `time.sleep(780)`(13 minutes) to your lambda code so that it 
runs for 13 minutes.
   
   Also decrease sleep time to 4 minutes and trigger the DAG multiple times 
quickly to reproduce ReadTimeout's
