[fzahabian]

Description:

I am trying to build and run a lambda locally using the sam cli but the build keeps failing with below error message
Error: GoModulesBuilder:Build - Builder Failed: go: go.mod file not found in current directory or any parent directory; see 'go help modules'

Steps to reproduce:

Here is my stack and command that I am running

• Mac OS 13.6 (22G120)
• docker engine v24.0.7
• SAM CLI, version 1.105.0
• docker image: public.ecr.aws/sam/build-go1.x:latest-x86_64

Build Template:
AWSTemplateFormatVersion: "2010-09-09" Transform: AWS::Serverless-2016-10-31 Resources: Function: Type: AWS::Serverless::Function Metadata: BuildMethod: go1.x Properties: Timeout: 300 MemorySize: 128 Handler: main CodeUri: /Users/zahaf002/go/src/app/liveactivity/ Runtime: go1.x

Build Command:
