Activation records and log messages not appearing for my Serverless Function

Question

I get no activation records or log messages when I run serverless functions via doctl. I have a working python 3.11 serverless function that does what I expect, except that logging doesn’t appear anywhere, and there are no activation records- $ doctl serverless activations list hello-world/mainy Datetime Status Kind Version Activation ID Start Wait Duration Function (no records, just headers) $ doctl serverless activations list Datetime Status Kind Version Activation ID Start Wait Duration Function (no records, just headers) $ doctl serverless activations logs -f hello-world/mainy (no output) $ doctl serverless activations logs (no output) I’ve run the function successfully a handful of times, and still nothing. Is there a latency period for logs to appear? I started yesterday, still seeing nothing today. Here is the function def- import json import logging logging.basicConfig(level=logging.DEBUG) logger = logging.getLogger(__name__) def main(args): try: logger.warning("Starting hello-world function") logger.warning(str(args)) logger.info("This is an info log") logger.debug("This is a debug log") name = args.get("name", "") if not name: name = "world" retval = { "statusCode": 200, "headers": { 'Content-Type': 'text/html', }, "body": f"""Hello, {name}

 Type: "{type(args)}" Class: "{args.__class__.__name__}" {json.dumps(args, indent=4, sort_keys=True)}

""", } logger.warning(f"Returning: {retval}") logger.error(f"Returning: {json.dumps(retval)}") return retval except Exception as e: logger.exception(e) return {"error": str(e)} project.yml: packages: - name: hello-world functions: - name: mainy parameters: runtime: "python:3.11" web: true limits: timeout: 10000 # 10 seconds memory: 512 DM me for URL / function UUID. Regarding third-party logging / log forwarding, I’d rather not use or pay for external logging while I’m just trying out Functions, you know what I mean? I’m want to get something working, to learn whether DO Functions meets my needs. If it looks production-worthy and I continue development, then I’ll sign up for external logging. At this point, I’m having to embed log type info into my response object, which isn’t ideal but it’s getting me by for now. Also fyi- the topic of local or non-external logging doesn’t appear to be covered in DO’s docs for basic stuff I’m having to rely on forums and LLMs to figure out how things work, because the docs are very limited. For example, How to Develop Functions shows output of logs via doctl, but there’s no code or project.yml provided to show how that was made possible There is a page on project.yml , but it’s just basic examples and doesn’t list all possible keys and values in a way similar to the App Platform app spec is… in other words, a comprehensive / complete schema is needed, otherwise we’re searching the web to find out what other developers have done I tried out DO’s LLM chatbot and it hallucinated doctl examples for commands and subcommands that do not exist

Hi there, If you’re calling the function via its public web: true URL, that might be why you’re not seeing any activation records or logs, I think that those only show up when you invoke the function using doctl. Also, sometimes the logging module doesn’t behave as expected in these lightweight runtimes. I’ve got logs working with log forwarding, but if you don’t want to try those aout, not 100% sure if there’s another issue here, so it might be worth reaching out to support for a closer look: https://do.co/support - Bobby
