nodejs18.x with arm64 issue

[reikje]

Describe the bug I am using the serverless framework successfully using nodejs16.x and arm64. When I bump to nodejs18.x and no further changes, I end up getting: Runtime.ImportModuleError: Error: Cannot find module 'handler' when executing the Lambda function - indicating some sort of transpile/build error.

I have not changed any esbuild related dependencies:

    "esbuild": "^0.15.7",
    "esbuild-node-externals": "^1.5.0",
    "serverless-esbuild": "^1.32.8",

Getting warnings in npm from esbuild-node-externals trying to use the latest esbuild version.

Which versions should I use to successfully build and deploy node18 / arm?

To Reproduce Try to set up a project that targets nodejs18.x and arm64 with serverless-esbuild and deploys a simple Hello World lambda function.

Expected behavior "Hello World" is returned when running curl against the deployed Lambda.

Did you solve this already? @reikje

Same issue here.

I am having a similar issue, I noticed that the generated .js file that invokes the function file is referring to an index.js file, and the function file is still a .ts file. There doesn't seem to be any transpilation from the source .ts file into a .js file. Downgrading to platform node14 fixed the problem for me, but I need node16x min for the main dependency I am using inside the lambda.

[rodrigomf24]

I found a fix, make sure you are using the latest version of serverless-esbuild, I bumped mine to 1.44.0 and it fixed the problem. I also want to clarify I have my platform configured to node16x and the esbuild config target to node16

Hmm... the OP already said that this works on node16x and the issue was updating to node18x.
