Function wrangler_below_min 

pub fn wrangler_below_min(probe: &Probe) -> bool

#1732: an installed wrangler older than [bynk_emit::WRANGLER_MIN], whose workerd therefore refuses the pinned [bynk_emit::COMPATIBILITY_DATE]. false for an npx-provisioned or unversioned wrangler, which can’t be judged without running it. Shared by doctor’s row and bynk dev’s notice.
