Getting error "fork/exec /var/task/main: no such file or directory" while executing aws-lambda function

Question

Getting error fork/exec /var/task/main: no such file or directory while executing lambda function.

I am using windows platform to run and build code in Go.

I have done following steps to deploy go aws-lambda handler:

1. Written code in go language with VSCode in windows platform
2. Build project with : go build main.go
3. Convert main.exe to main.zip
4. Uploaded main.zip with handler name main aws-lambda fuction using aws console account
5. Created test event to test lambda function
6. Got error "fork/exec /var/task/main: no such file or directory while executing lambda function"

package main  import (     "fmt"      "github.com/aws/aws-lambda-go/lambda" )  // Request represents the requested object type Request struct {     ID    int    `json:"ID"`     Value string `json:"Value"` }  // Response represents the Response object type Response struct {     Message string `json:"Message"`     Ok      bool   `json:"Ok"` }  // Handler represents the Handler of lambda func Handler(request Request) (Response, error) {     return Response{         Message: fmt.Sprint("Process Request Id %f", request.ID),         Ok:      true,     }, nil }  func main() {     lambda.Start(Handler) } 

build command

go build main.go

Log Output in AWS console

Answer 1

In my case the problem was default setted handler to 'hello' function.

Needed to change it to 'main' via AWS Lambda view panel -> Basic Settings -> Edit.
