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):

      expected_options = {
        redis_url: gitlab_redis_queues.url,
        sentinels: gitlab_redis_queues.sentinels
      }
      expected_inbox_options = {
        tenant_id: '1****',
        client_id: 'MY-C****T-ID',
        client_secret: 'MY-CLI****SECRET',
        poll_interval: 60
      }

      expect(configuration[:mailboxes].length).to eq(2)
      expect(configuration[:mailboxes]).to all(include(expected_mailbox))

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

Sincerely,
Emma
