This is causing a panic when info.Addr == nil. You need to add a check for that.

HI @mapno,
Thanks for the reviews, for version v0.74.0 of the opentelemetry-collector SDK, info.Addr is not a pointer. we should pay attention to future updates.

net.Addr is an interface, so it panics when undefined. See example https://go.dev/play/p/dx6a1BYB16J.
