Bug: sam build GoModulesBuilder fails to output the relevant error message, outputs "directory not found" instead #676
Description
Description:
When my Go code has a syntax error, I expect sam build to display the error. Instead, it's showing a generic error:
Error: GoModulesBuilder:Build - Builder Failed: stat /Users/my.user/my-project/myproject/bootstrap: directory not found
In my template.yaml, here's the relevant block for my Go lambda:
Resources:
MyFunction:
Type: AWS::Serverless::Function # More info about Function Resource: https://github.com/awslabs/serverless-application-model/blob/master/versions/2016-10-31.md#awsserverlessfunction
Metadata:
BuildMethod: go1.x
Properties:
CodeUri: myproject/
Handler: bootstrap
Runtime: provided.al2023
Architectures:
- x86_64
I have a file myproject/bootstrap.go that contains func main() { lambda.Start(handler) }.
Steps to reproduce:
Create any syntax error, like renaming a function from MyFunc to MyFunc2
Observed result:
A "directory not found" error.
Expected result:
The output from go build which shows the actual error.
