OCI Functions: Timeout Errors When Invoking Function With Large Payloads from Python

Can someone help me understand I've encountered a strange issue with After trying multiple solutions online, I still can't figure this out... I am working on an OCI Function that processes large JSON payloads, but I'm working with timeout errors when invoking the function from my Python application. The function is deployed using the OCI Functions CLI, and it has a timeout set to 60 seconds. However, when I send payloads over 5 MB, the function times out, and I see the following behavior in the OCI logs: ``` behavior: Function invocation timed out after 60 seconds. ``` I have tried optimizing the function's logic and reducing the payload size, but since the function is meant to handle large data, that isn't a viable option. Hereโ€™s a simplified version of what my function looks like: ```python import json def handler(ctx, data: str) -> str: payload = json.loads(data) # Process large payload here return 'Processed successfully' ``` I am invoking this function using the `oci.functions.FunctionsManagementClient` in Python, like so: ```python import oci client = oci.functions.FunctionsManagementClient(config) response = client.invoke_function( function_id='your_function_id', invoke_function_body=json.dumps(your_large_payload), ) ``` I confirmed that the function does work with smaller payloads (around 2 MB) without timing out, but any attempt to send the larger payload leads to the timeout scenario. Iโ€™ve also increased the timeout value in the function configuration, but it seems like thereโ€™s a limitation when handling larger payloads in one go. Is there a best practice for handling large payloads in OCI Functions? Should I consider chunking the data, or is there an alternative approach that can work around this limitation? Am I missing something obvious? I recently upgraded to Python 3.10. I'd be grateful for any help. What's the correct way to implement this?
