Error message

store %v: %w

What it means

StoreSecret wraps failures from client.Store(prog.runner, cred) as 'store <store>: <cause>'. The credential object was built fine, but the external store program refused or failed the write. The inner error after the store name carries the real reason.

Solutions

Inspect the wrapped cause after 'store <store>:' and address it
Test the store manually (e.g. `pass insert test`) with the same user/environment
Unlock the keychain / ensure gpg-agent is available and the GPG key is initialized
Fix filesystem permissions or disk issues on the store path
Check the secretStore runner configuration points at a working, executable binary

Example fix

# before (headless, keychain locked)
wtf.secretStore.type: keychain
# after
wtf.secretStore:
  type: pass
  # pass works headlessly once GNUPGHOME + key are initialized

Defensive patterns

Strategy: try-catch

Validate before calling

// ensure backend reachable before writing
if out, err := exec.Command(storeCmd, "ls").CombinedOutput(); err != nil {
    return fmt.Errorf("store backend unhealthy: %s: %w", out, err)
}

Try / catch

if err := cfg.StoreSecret(conf, secret); err != nil {
    if unwrapped := errors.Unwrap(err); unwrapped != nil {
        log.Printf("store write failed: %v", unwrapped) // e.g. gpg/keychain error
    }
    return err
}

Prevention

Unlock the keychain / ensure gpg-agent before headless runs
Verify store directory permissions and free disk space
Test writes manually: pass insert wtf-test
Run the store helper as the same user wtfutil runs as

When it happens

Trigger: Writing to a pass store with no initialized GPG key; keychain denied access (locked or ACL prompt rejected); read-only or missing store directory; the runner binary exiting nonzero; store rejecting an entry with empty username (code defaults it to "default", but empty service/secret can still fail).

Common situations: Headless servers without keychain access; disk full or permissions on ~/.password-store; passphrase-protected GPG key prompting in a non-interactive terminal; SELinux/AppArmor blocking the helper binary.
