"[ERROR] OSError: [Errno 38] Function not implemented" - Accessing trend deepsecurity.ComputersApi via Lambda

I have written a python script that successfully queries the trend deepsecurity api calls when ran locally on my machine. I've been tasked with running the script in an aws lambda so that it is automated and can be scheduled.

The script is following the examples in the api reference and calls the legacy api successfully. However when I attempt to query using the computers api It blows up on the line : computers_api = deepsecurity.ComputersApi(deepsecurity.ApiClient(configuration))

def get_computer_status_api():
    # Include computer status information in the returned Computer objects
    #expand = deepsecurity.Expand(deepsecurity.Expand.computer_status)
    expand = deepsecurity.Expand()
    expand.add(deepsecurity.Expand.security_updates)
    expand.add(deepsecurity.Expand.computer_status)
    expand.add(deepsecurity.Expand.anti_malware)

    # Set Any Required Values
    computers_api = deepsecurity.ComputersApi(deepsecurity.ApiClient(configuration))

    try:
        computers = computers_api.list_computers(api_version, expand=expand.list(), overrides=False)
        print("Querying ComputersApi...")
        api_response_str=str(computers)
        computer_count = len(computers.computers)
        print(str(computer_count) + " Computers listed in Trend")
    ...

the error I get is :

    sl = self._semlock = _multiprocessing.SemLock(

searching for this error it implies that I can't use the deepsecurity api in a lambda because lambdas don't support multiprocessing.

Looking for either confirmation that this is the case or suggestions for what I can change to get this working.

Solution

  • Resolved the issue by changing the python version from 3.8 to 3.7 in the lambda. The script now runs successfully
