I've been using delv via a skaffold config to run debugging on an app deployed in kubernetes in vs code. This had been working great. However today I updated to go 1.20, and started having issues. Now after I run my skaffold debug (-p debug), and then Attach to Kubernetes, I get a debug console error:

Failed to halt delve before attempting to set breakpoint: "Internal debugger error: <nil> not an Int runtime.gopanic (0x435591) /usr/local/go/src/runtime/panic.go:884 go/constant.Int64Val (0x591873)

Anyone run into this, in general or after updating to 1.20.2?

The full error I'm getting below:

What version of delve are you using? There was a bug like this with using older versions of delve with go 1.20.
