Poem

🐰 I nibble at modules, one hop at a time,
I tuck a new field where the proto bells chime,
Dependencies pruned and versions in line,
A tiny change made, the build sings—so fine! 🎋

just doublechecking - this (p.params.ClientInfo.ClientInfo) can't be nil - right?

[boks1971]

It should not be, but good point, will add a check
