Bug: Debug Portal not working with sam local start-api dlv and VSCODE

[andrewbohm]

Description:

Debug port is not opening up when running sam local command below. only port 5001 is exposed

Steps to reproduce:

1. sam build
2. sam local start-api -p 5001-d 8099 --debugger-path={CORRECT PATH TO dlv} --debug-args="-delveAPI=2"

Observed result:

sam local start-api -p 5001-d 8099 --debugger-path={CORRECT PATH TO dlv} --debug-args="-delveAPI=2" OUTPUT:

Mounting LambdaFunctionName at http://127.0.0.1:5001/animal [POST]
Mounting LambdaFunctionName2 at http://127.0.0.1:5001/name [POST]
Mounting LambdaFunctionName3 at http://127.0.0.1:5001/address [POST]
You can now browse to the above endpoints to invoke your functions. You do not need to restart/reload SAM CLI while working on your functions, changes will be reflected instantly/automatically. You only need to restart SAM CLI if you update your AWS SAM template

launch.json:

{
        "name": "Debug with sam",
        "type": "go",
        "request": "attach",
        "mode": "remote",
        "port": 8991,
        "host": "localhost"
},

Expected result:

To show debug section in output and show debug port opened. When running Debug With SAM in VSCODE I would expect it to attach correctly and not state the following: Failed to continue: "Error: connect ECONNREFUSED 127.0.0.1:8991"

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

1. OS: Windows WSLv2 Linux Ubuntu
2. sam --version: 1.56.1
3. AWS region: N/A - local run

Add --debug flag to command you are running

Thanks for reporting this issue.

I've tried using AWS Toolkit's shortcut (which displays on top of the API definition) to start the debugging session. I was able to attach debugger and start debugging.

Can you try with that approach and see if it is working?

[andrewbohm]

@mndeveci Thanks for responding. I do not see AWS toolkit shortcut you are stating. I did try try the "AWS: Add Debug Configuration" with no avail.
See screenshot:

[mndeveci]

There is one before the Events property, which says AWS: Add API Debug Configuration, can you try that one and see if it is going to stop at breaking point?

[andrewbohm]

No luck.
Same results with both Add Debug configuration settings.

Are there any news on this issue? I'm experiencing the same thing on my laptop...
