Security-related question about a possible exposed credential

[Emma-NYL]

Hello,

My name is Emma, I am conducting an academic study on possible credential exposure in public GitHub repositories.

While analyzing this repository, I found a string that may represent a credential. I'm including the code snippet below containing possible leakage. To avoid exposing sensitive information publicly, I marked the sensitive information.

Could you please help clarify whether the detected string is:

1. a real credential, or
2. a placeholder / example value?

Thank you for your time.

Code snippet (sensitive values masked):

const defaultConfig = {
  TROCIO_URL: 'https****roc.io',
  TROCIO_OCD_API_KEY: '', // API key provide by https://opencagedata.com/
  TROCIO_ROOT_USER: '', // Root user email
  TROCIO_SECRET_STRING_COOKIE: '', // A secret string for secure cookies
  TROCIO_SMTP_PASS: "Your_****word'', // password of your SMTP server
  TROCIO_SMTP_USER: 'salu****oc.io',
  TROCIO_SMTP_HOST: 'smtp.ho****ger.com',
  TROCIO_SMTP_PORT: 465,
  TROCIO_PORT,
  TROCIO_API_PORT: 5001,
  TROCIO_DB: 'mongodb://loca****t:27017/trocio',
  TROCIO_BACKUP: '.****mp',

Thank you in advance for your time - I really appreciate it!

Sincerely,
Emma
