reading config updte envelope: %s

Error message

reading config updte envelope: %s

What it means

osnadmin wraps any failure reading the file given via --configUpdateEnvelope with this error (note the 'updte' typo is in the message itself). It occurs before the envelope is parsed or validated against the channel ID.

Solutions

1. Verify the --configUpdateEnvelope path exists and is readable.
2. Use an absolute path.
3. Check file permissions.
4. Regenerate the envelope with configtxgen if missing.

Example fix

// before
osnadmin channel update --channelID mychannel --configUpdateEnvelope env.pb
// after
osnadmin channel update --channelID mychannel --configUpdateEnvelope /absolute/path/to/config_update_envelope.pb

path := "./config_update_envelope.pb"
if fi, err := os.Stat(path); err != nil || fi.IsDir() {
    return fmt.Errorf("envelope %s missing or invalid: %w", path, err)
}

func fileExistsNonEmpty(path string) bool {
    fi, err := os.Stat(path)
    return err == nil && !fi.IsDir() && fi.Size() > 0
}

if err := runOsnadmin(); err != nil {
    if strings.Contains(err.Error(), "reading config updte envelope:") {
        log.Fatalf("check --configUpdateEnvelope path: %v", err)
    }
}

When it happens

Trigger: Running `osnadmin channel update` with a --configUpdateEnvelope path that does not exist, is unreadable, or is a directory.

Common situations: Typo in envelope file path, envelope produced by configtxgen placed elsewhere, permission issues after copying between hosts or containers.

Understand the failure class

Background: "File not found" and ENOENT errors: why libraries can't find a file that should exist — this error's family across 50 libraries.
