Песочница JazzCash: транзакция не удалась с кодом ответа 199 ⇐ Php

[Anonymous]

Я тестирую изолированную среду JazzCash для обработки платежей в своем приложении Laravel, но столкнулся с проблемой. Транзакция не удалась, и возвращается код ответа 199 с сообщением:
**"Извините! Ваша транзакция не прошла успешно. Повторите попытку позже".

**What I've Tried**
Verified that all required fields are correctly formatted and filled.
Ensured that the pp_SecureHash is generated using the correct algorithm and matches the expected format.
Confirmed that the sandbox credentials provided by JazzCash are correct.
Checked the pp_ReturnURL to make sure it is accessible (using Ngrok).
Questions
What does the response code 199 signify in the JazzCash sandbox environment?

----------

Could there be an issue with my sandbox credentials or environment setup?
How can I resolve this to successfully test the transaction in the sandbox?
