Looks like it is possible to move the bootstrap script into the layer: https://docs.aws.amazon.com/lambda/latest/dg/runtimes-walkthrough.html

From https://docs.aws.amazon.com/lambda/latest/dg/runtimes-custom.html:

Create a context object – Create an object with context information from environment variables and headers in the API response.

Hi Toni, great project! I found it through your post on the Swift forums.

I modified your project to write my own little function. Since my function uses Swift 5 features, I switched the Docker image to codevapor/swift:5.0.

Everything seemed to work, but when I tested my function on AWS, it failed with:

error while loading shared libraries: libswiftDispatch.so: cannot open shared object file: No such file or directory

It looks like the source of this error is that the names of one or more shared libraries changed in Swift 5, e.g. libdispatch.so is now called libswiftDispatch.so. So I need to update the list of shared libraries in the Makefile. Can I ask how you generated this list?

Running ldd [path_to_my_binary] on Linux seems to be an option to get a list of the shared libraries loaded by an executable, but I wanted to ask if you used a different option.

Thanks and happy holidays!

PS: Don't let me stop you from enjoying your holidays. This isn't urgent.

Where is your docker file so we can create this runtime ?

Or, can you post the runtime zip somewhere others can just download it ?

A great project. I love Swift and AWS and I am looking to combine the two with your amazing work and hoping to contribute in the future if I can.

I do have an issue when creating the swift-runtime zip file. I do feel that I am getting a user side error when running the make package_layer command. I receive the following errors:
cp: cannot stat '/lib/x86_64-linux-gnu/libcrypto.so.1.0.0': No such file or directory cp: cannot stat '/lib/x86_64-linux-gnu/libssl.so.1.0.0': No such file or directory cp: cannot stat '/usr/lib/x86_64-linux-gnu/libicudata.so.55': No such file or directory cp: cannot stat '/usr/lib/x86_64-linux-gnu/libicui18n.so.55': No such file or directory cp: cannot stat '/usr/lib/x86_64-linux-gnu/libicuuc.so.55': No such file or directory cp: cannot stat '/usr/lib/x86_64-linux-gnu/libidn.so.11': No such file or directory make: *** [package_layer] Error 1

I do feel like I am missing those libraries locally but can't seem to figure out the installion of them. Any help will be appreciate. (I do feel like this is a beginner issue so apologies in advance.)

From https://docs.aws.amazon.com/lambda/latest/dg/runtimes-custom.html:

Handle errors – If an error occurs, call the invocation error API.

Propagate the tracing header – Get the X-Ray tracing header from the Lambda-Runtime-Trace-Id header in the API response. Set the _X_AMZN_TRACE_ID environment variable with the same value for the X-Ray SDK to use.

This is a lambda function with proxy integration connected to an API Gateway.
It randomly crashes with this log:

It seems to have something to do with URLSession on Linux. I have tried to print more info, but all I could get was: Foundation.URLError(_nsError: The operation could not be completed.

Also, both HTTPResponse and data are empty.

@tonisuter thoughts?

Hi,

I was wondering, if it would make sense to replace the current http client implementation based on URLSession and FoundationNetworking with an implementation based on
