Debugging Lambda in VSCode dlv and sam not found (CPU: M2, Template: go 1.x image)

rei-gun commented 1 year ago

Problem

Steps to reproduce the issue

It seems like VSCode/AWS-Toolkit can't access my OS's path because it always complains that delve can't be found (even though I can access it via VSCode's and my OS' terminal) and it can't find sam either.

Expected behavior

function is invoked and breakpoints are hit

System details (run the `AWS: About Toolkit` command)

OS: Ventura 13.1 (Darwin arm64 22.2.0)
Visual Studio Code version: 1.74.2
AWS Toolkit version: 1.60.0
SAM CLI version: 1.67.0

@rei-gun

This might be related to this SAM CLI issue. Could you try downgrading SAM CLI or using one of the solutions in the comments and report back? Manually changing a dependency seems like it might work if downgrading doesn't.

rei-gun commented 1 year ago

I've tried using the script here, to downgrade to 1.64.0 and 1.65.0 but both not found

reigun@ip-192-168-68-70 work % ./brewv.sh aws-sam-cli 1.65.0
fatal: --unshallow on a complete repository does not make sense
Homebrew repo already unshallowed
No version matching '1.65.0' for 'aws-sam-cli'

Previous versions of the CLI don't seem to be available in homebrew?

reigun@ip-192-168-68-70 work % brew search '/^aws-sam-cli$|^aws-sam-cli@/'
Error: No formulae or casks found for "/^aws-sam-cli$|^aws-sam-cli@/".

With regards to manually changing a dependency, which one would I change? The post you've linked talks exclusively about a Python Lambda function whereas I am using Go

Architectures:

- arm64
  - x86_64

As a workaround / for troubleshooting, can you try - arm64, see https://github.com/aws/aws-toolkit-vscode/issues/1566#issuecomment-1268636183

aws / aws-toolkit-vscode
