Async (Event) Function Invocation Emulation?
doransmestad opened this issue · comments
Hello there! First off, thank you for making this emulator, it is really helpful for testing and development.
My question: is there a way to run the function invocation asynchronously? As far as I can tell, right now the HTTP request to the emulator results in a blocking call (i.e. no HTTP response until the function completes). This is helpful for testing the RequestResponse invocations, but causes issues with code using Event invocations (https://docs.aws.amazon.com/lambda/latest/dg/API_Invoke.html#API_Invoke_RequestSyntax).
In other words, I would expect the follow curl command to return almost immediately even if the "lambda" started takes a few minutes to complete.
curl -v -XPOST "http://localhost:9000/2015-03-31/functions/function/invocations" -H "X-Amz-Invocation-Type: Event" -d '{}'
Not having this unfortunately breaks code that relies on the Event (async) behavior. We can of course thread/async those calls in our code, but it breaks the emulation we were hoping for.
Am I missing something, or is this indeed currently not covered by the emulator? If not covered, would a pull request to add it be welcome?
Thanks.
I have exactly the same issue.
@doransmestad have you found a solution?
@valerena Sorry for directly tagging you into this but I saw you as the most active contributor. I'm also facing the same issue of not being able to use InvocationType Event and I saw this issue kind of inactive. Is there a way to have this working?
