Go Function always fails with permission denied

[NHirom]

Description:

As written in the title, Go function always fails with a permission denied error. I have just followed the instruction written in the below page to compile dlv and my go binary. https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-using-debugging-golang.html

Of course, I have checked permissions of those binaries and those were executable for all users.

Steps to reproduce the issue:

1. execute "sam local start-api -d 5986 --debugger-path debug"
2. kick "curl http://127.0.0.1:3000/test"
3. Error occurs

Observed result:

Expected result:

my go binary runs

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

sam cli version -> 0.6.0 and upper go -> 1.10 dlv -> 1.0.0 and upper

Is this because of docker image build done 6days ago? https://hub.docker.com/r/lambci/lambda/

I have seen a blog post that says the instruction had been working until two months ago.

@NHirom What is in the debug directory you are passing in --debugger-path?
