Golang Debugging - Error starting Mock Server

I've been trying to get step through debugging working following the guide on MacOS 11.1. Starting with the basic hello-world template I'm able to build the project and run it locally. If I follow the guide and build delve and the application as instructed, I receive an error message stating Error starting mock server: fork/exec /var/rapid/init: no such file or directory are these instructions missing some details around setup?
My project is structured as:
.
├── .aws-sam
│ ├── build
│ │ ├── HelloWorldFunction
│ │ │ └── hello-world
│ │ ├── delve
│ │ │ └── dlv
│ │ └── template.yaml
│ └── build.toml
├── Makefile
├── README.md
├── hello-world
│ ├── go.mod
│ ├── go.sum
│ ├── main.go
│ └── main_test.go
└── template.yaml
The template file has not been changed from the sample application.
I've added the following debug section to the Makefile:
.PHONY: debug

For future reference this appears to related to aws/aws-sam-cli#2462. If I install sam cli version 1.12.0 the instructions work fine.
