Delve not creating __debug_bin file

Question

I'm a little stuck... I'm trying to get Delve to run in my docker container but it keeps exiting with the same error:

could not launch process: fork/exec /my/project/__debug_bin: function not implemented

When I've used Delve in other projects this __debug_bin file was created automatically by Delve and then removed after the debugging finished. But here it looks like it's not creating it?

Anyone know why or what I can do to debug this debugger further and find out the cause?

Here's the relevant part of my Dockerfile and docker-compose.yml:

Dockerfile Delve installation

RUN go get github.com/go-delve/delve/cmd/dlv

RUN go mod vendor

RUN go install -gcflags="all=-N -l" -ldflags "-X main.version=$BUILD_VERSION" ./cmd/billing

docker-compose.yml

    billing:
        image: my/image
        restart: unless-stopped
        depends_on:
            db:
                condition: service_healthy
        volumes:
            - .:/my/project/path
        ports:
            - "${DEV_ENV_HOST:-0.0.0.0}:9800:9800" # main app port
            - "${DEV_ENV_HOST:-0.0.0.0}:40000:40000" # debugger port

And here's my delve command:

dlv debug --headless --listen=:40000 --api-version=2 --accept-multiclient --check-go-version=false ./cmd/billing

I can't think of what else to try to get this to work...
