What did you do?

The process is running inside a container with base image centos-micro:7.9-22.0,
by calling:

/opt/health/healthClient <port_number>

What did you expect to see?

To create a client connection:

[HOME]/src/health/healthClient/main.go:21
conn, err := grpc.Dial(port, grpc.WithInsecure())
if err != nil {
l4g.Fatal("did not connect: %s", err)
}

What did you see instead?

panic: runtime error: invalid memory address or nil pointer dereference

It is not clear to me why this would be a Go problem as opposed to a grpc problem. Have you filed this issue with grpc first?

Please confirm that you are not actually running Go 1.6.5, a release that never existed and would be long out of support if it did exist.

The "go env" blurb cited above includes this:

GOVERSION="go1.17.1"

so I hopefully the 1.6.5 is just a typo.

Sorry it was actually a typo. The version was go 1.16.5.
The code build is part of Jenkins pipeline and the go version has been updated. The go version is the only change regarding the go env variables.
