Debug Node AWS Lambda Function with serverless offline causes Error

[ManuelMos]

This is a Bug Report

Description

• My Environment: Windows 10, node.js 10.15.0, sls 1.36.1.

I try to debug my nodejs lambda function with serverless offline.

Running
node --inspect node_modules/.bin/serverless offline

causes:

basedir=(dirname "(echo “$0” | sed -e ‘s,,/,g’)")
^^^^^^^
SyntaxError: missing ) after argument list

Same when i try to run it in intellij:

Hi @ManuelMos,
It seems that the issue concerns vm.js, i.e. Nodejs's core.
can you check that node --inspect node_modules/.bin/serverless offline is actually node --inspect node_modules/.bin/serverless-offline ?

Hello, I'm having the same issue.

I'm on Ubuntu 18.04.1 LTS, with Node v8.15.1, serverless v1.40.0 and serverless-offline 3.33.0

I have checked and there is not a hypen, there is a space. Putting a hypen gives a completely different error:
Error: Cannot find module '/my/project/path/node_modules/.bin/serverless-offline' at Function.Module._resolveFilename (module.js:548:15) at Function.Module._load (module.js:475:25) at Function.Module.runMain (module.js:694:10) at startup (bootstrap_node.js:204:16) at bootstrap_node.js:625:3

@ManuelMos @ocramot If you are still having this issue, could you try:

node --inspect ./node_modules/.bin/serverless offline (notice the dot slash)

may be related to (although this mentions only node v11.x): nodejs/node#25967

feel free to re-open if you think this is an issue with serverless-offline.

Hello i had same issue on my Windows 10, managed to solve it by changing the path as shown bellow.

"debug": "SET SLS_DEBUG=* && node --inspect %USERPROFILE%\\AppData\\Roaming\\npm\\node_modules\\serverless\\bin\\serverless offline -s dev",
