Hello. I'm trying this, following whats in the README and getting to the stepaws lambda invoke for the basic example and it fails with:

RequestId: 22649496-f719-11e8-b4b6-c796ae152b7e Error: Runtime failed to start: fork/exec /var/task/bootstrap: exec format error
Runtime.ExitError

Any ideas?

Hey @torntrousers, I suspect because the target platform. If you are using a Mac, you can follow the tutorial here. Otherwise, use an Amazon Linux Docker container - I posted a Dockerfile definition here

Thanks, I am using a Mac and I followed that tutorial and was able to get the basic example working. Yay! It wasn't totally straight forward though and needed a few attempts to fix it. I'll see if can write up the minimal steps. Might be good to mention the building on a Mac complications in the README here.

Ran into this transiently on windows too, with another custom runtime.

If you are a serverless framework user you may want to check out the rust plugin It provides a more seemless build experience as it uses the lambdaci project's "provided" build env ( a faithful replication of the same env you will be deploying into )

for me, it's the problem with the platform. I was on mac with an m1 chip. After setting the architecture to x86_64 worked for me.
