Debug Node AWS Lambda Function in IntelliJ with serverless offline

Serverless Framework
,

Hi,

I try to debug my node js lambda function with serverless offline.

after some googling i found that

node --inspect node_modules/.bin/serverless offline

should work. But when i try to run it i get:

basedir=(dirname "(echo “$0” | sed -e ‘s,\,/,g’)")
^^^^^^^

Any ideas?

Assuming you want to be able to run your lambdas in serverless-offline from IntelliJ, setup a run/debug configuration as in the attached screenshot:

If you don’t have sls installed globally, set “JavaScript file:” option to location of serverless in your local node_modules.

This setup has worked for me, and with it you can set breakpoints and step through your lambda code within IntelliJ

Hi, thanks for your response.
I guess i will have to open an github issue. Only difference is i am running on windows.
I did the same thing but i still get the exception:

Waiting for the debugger to disconnect…

This works fine in IntelliJ on Windows: the entry javascript file needs to be something like:

node_modules\serverless\bin\serverless.js

(The file in node_modules\.bin\sls is a shell script, not a javascript file)
