Error: Cannot find module 's_index' when serverless enterprise is enabled

[artworx]

This is my serverless.yml file:

...
 functions:
    index:
      handler: dist/index.handler
...

The deployed Lamba's entry point gets set to s_index.handler, but when serverless-plugin-tree-shake is enabled, that file is not present in the deployment.

thanks for the report, I'm a bit busy right now, but I'll check this out once I have some time.

One thing to check: do you have any plugin compiling the files into dist/index.js? If so, is that step happening when you add serverless-plugin-tree-shake?

[artworx]

I don't have any extra plugins for compiling

This is the minimal serverless.yml I used to reproduce it.

org: artworx
app: demo
service: lambda-demo

provider:
  name: aws
  runtime: nodejs12.x
  region: eu-central-1
  stage: dev

plugins
  - serverless-plugin-tree-shake

functions:
  hello:
    handler: handler.main

As soon as I add org and app keys to serverless.yml, the handler in cloud formation is s_handler.

# .serverless/serverless-state.json

          "HelloLambdaFunction": {
            "Type": "AWS::Lambda::Function",
            "Properties": {
              "Code": {
                "S3Bucket": {
                  "Ref": "ServerlessDeploymentBucket"
                },
                "S3Key": "serverless/...
              },
              "Handler": "s_hello.handler",

If I remove the serverless-plugin-tree-shake, the packaged zip file includes s_handler.

edit: without the plugin:

But notice that in your second snippet you no longer have the dist/ in the handler. Any reason why?

[artworx]

Because i created a new project with just a single js file. It's not about the compilation, its about the injected wrapper by the serverless framework which gets stripped from the final package.
