credentials: missing password `search` field

Error message

credentials: missing password `search` field

What it means

Thrown when the phishlet's credentials.password block is missing the 'search' field. 'search' is the regex extracting the password value from the POST body; without it captured passwords cannot be parsed, so the phishlet is rejected.

Solutions

  1. Add 'search: <capture regex>' under credentials.password
  2. Ensure key and search are siblings within credentials.password
  3. Re-validate the phishlet after the edit

Example fix

// before
credentials:
  password:
    key: 'password'
// after
credentials:
  password:
    key: 'password'
    search: 'password=([^&]*)'
Defensive patterns

Strategy: validation

Validate before calling

if cfg.Credentials.Password.Search == nil || *cfg.Credentials.Password.Search == "" {
  return errors.New("credentials: missing password search")
}

Type guard

func hasPasswordSearch(fp FakePost) bool { return fp.Credentials.Password.Search != nil && *fp.Credentials.Password.Search != "" }

Prevention

When it happens

Trigger: A phishlet YAML defines credentials.password.key but omits 'search', or 'search' is misplaced by indentation.

Common situations: Writing password block with key only; copy-paste losing the search line; editing that accidentally removed it.
