generating badge id: %v

Error message

generating badge id: %v

What it means

When setting (not clearing) a badge, badgeRun generates a unique badge id with uuid.NewV7(). If UUID generation fails (e.g. insufficient system entropy), the error is wrapped as "generating badge id: %v".

Solutions

1. Check the host's entropy source is available (e.g. /dev/urandom readable inside containers).
2. Re-run the command — entropy failures are often transient.
3. Fix container security settings (seccomp/device restrictions) that block random device access.

badgeId, err := uuid.NewV7()
if err != nil {
    // retry once; if persistent, check host entropy (/dev/urandom)
}

When it happens

Trigger: uuid.NewV7() returns an error — typically crypto/rand unavailable or the underlying entropy source failing on the host.

Common situations: Running in a heavily restricted container/OS sandbox where /dev/urandom or the crypto entropy pool is unavailable; corrupted Go crypto runtime — rare in practice.
