`undefined behavior - version of Delve is too old for Go version 1.22.3 (maximum supported version 1.20)`

I am trying to debug a Kubernetes operator built using golang 1.22.3. I am seeing these errors when I run skaffold debug:

...
[manager] API server listening at: [::]:56268
[manager] 2024-06-24T17:29:11Z warning layer=rpc Listening for remote connections (connections are not authenticated nor encrypted)
[manager] 2024-06-24T17:29:12Z error layer=debugger could not patch runtime.mallogc: no type entry found, use 'types' for a list of valid types
[manager] WARNING: undefined behavior - version of Delve is too old for Go version 1.22.3 (maximum supported version 1.20)
...

When I attempt to attach VSCode or use dlv from the command line, I see 1. in the case of VSCode or sometimes 2. in the case of dlv connect 127.0.0.1:56268:

1. [manager] 2024-06-24T17:33:14Z error layer=rpc writing response:write tcp 127.0.0.1:56268->127.0.0.1:39128: write: broken pipe

Environment

For whatever reason skaffold is installing version 1.20.x of delve which is too old for the version of go that you are using. You should report this problem to them.
